The wild heart of Katmai National Park harbors 14 active volcanoes.

This national park of around 5 million acres surpasses the magnificence of the Grand Canyon National Park.

Kayaking, canoeing, and hiking here are one-of-a-kind experiences. 

One of the oldest national parks, Katmai National Park, was established in 1918.

Novarupta Volcano eruption on 6th June 1912 was destructive, and preservation of the habitation around Mount Katmai was crucial.  

The National Park Service website says, 

“Lasting three days, the largest volcanic eruption of the twentieth century exploded June 6, 1912, from a new volcano, Novarupta.

In the process, it created Katmai caldera and the Valley of Ten Thousand Smokes.

Not only have the 1912 events remained scientifically important ever since, but also the 1912 deposits continue to provide insights about volcanic and magmatic processes that impact us and the land we live in.” (Source) 

Today, this national park is a living account of human history, and it is the home for brown bears and salmon.

It is also one of the most popular destinations for volcanologists because it’s still active.

Further, it has a handsome number of visitors every year, and in 2023, the number of visitors was 33,763. (Source) 

Do you also want to explore this magnificent volcanic landscape? Let me be your guide. 

Why Are So Many Volcanoes In Katmai National Park?  

With “50 discrete volcanic vents,” Katmai National Park is the center of attention for many.

But why does it have so many volcanoes? 

Volcanoes in the Aleutian volcanic arc and Katmai National Park are part of the Pacific Ring of Fire.

“The Ring of Fire is home to 75% of the world’s volcanoes and 90% of its earthquakes.” (Source) 

Many call the Ring of Fire the Circum-Pacific Belt, and many tectonic plates meet here.

Due to the constant movements of these plates (especially the subduction of the Oceanic Pacific Plate under the North American Plate every year), volcanic eruptions and earthquakes take place here.  

Along with the eruption of  Novarupta-Katmai in 1912, there are also records of the eruption of Mount Trident from 1953 to 1974.  

The latest volcanic eruption in Katmai happened with the venting of Fourpeaked Volcano in 2006.

Here is an excerpt from a report published on the 2006 volcanic eruption of Fourpeaked Volcano.  

“On September 17, 2006, Fourpeaked Mountain, a glacier-clad stratovolcano with no known Holocene activity, produced a plume of steam, ash, and SO2, which rose to 6000 m above sea level.

The plume was observed by eyewitnesses, seen on weather radar, and also appeared in SO2-sensitive satellite imagery.

Concurrent with the plume, regional seismic stations recorded a swarm of volcano-tectonic earthquakes while an atmospheric infrasound signal was recorded 800 km away.

Air and ground reconnaissance revealed a linear series of vigorously steaming vents in the summit glacier, stretching about 1 km down the north flank of the volcano.” 

So, are you ready to learn about the active and rugged volcanoes in Katmai National Park?

The next section gives you a detailed overview.  

Know The Volcanoes In Katmai National Park 

Know The Volcanoes In Katmai National Park 

Volcanoes erupt for a short span if you study the entire timetable of a volcano.

However, the eruption is only the outcome of activities that take place for years or even centuries.

Similarly, the volcanoes in Katmai National Park have faced long intermittent periods between the occurrences of small and big eruptions.  

Further, the volcanic activities and earthquakes taking place in Katmai due to tectonic movements have a major impact on human lives across generations.  

Here, I present a brief overview of a few volcanoes out of the 14 in Katmai. 

Mount Katmai 

Mount Katmai has recorded the highest explosive incidents in the Katmai volcanic cluster.

Active for over 70,000 years, the two cones of Mount Katmai were beheaded due to the caldera collapse in 1912.   

The eruptive products of Mount Katmai are varied in their compositions, including basalt and rhyodacite.  

Mount Griggs

Mount Griggs, the tallest peak in the district, is 2,530 m tall.

Despite having young lava flows, some of the deposits in Mount Griggs are 290,000 years old.  

The volcano is still active, and you will get to see the yellow sulfurous steam around its summit.  

Trident Volcano

Trident Volcano is one of the older volcanoes in Katmai. From 1953 to 1974, Trident Volcano had many eruptions.

However, the highest and central volcanic cone of Trident Volcano has been lying dormant for around 10000 years.  

Mount Mageik 

Mount Mageik has four discrete eruptive centers covered with snow.

However, glaciers have caused severe decay in three of these lava centers.

It is a younger volcano in Katmai, with its lava aged between 4,000 and 93,000.  

The last eruption of Mount Mageik happened 2500 years ago.

It caused a crater between two Mount Mageik summits. Today, the crater is filled with an acid lake, exuding steam curls.  

Alagogshak Volcano 

Alagogshak Volcano

Alagogshak stands at the southwesternmost corner of the Katmai volcanic cluster.

It is also the oldest in the Katmai family of volcanoes. The lavas in this volcano are 40,000-680,000 years old.  

Peak 6875, Snowy Mountain  

Peak 6875 is a young dome made of dacite lava.

The scoop-shaped peak looks like a natural amphitheater.   

Spectacular Landscapes Created By Volcanic Activities In Katmai National Park  

Volcanic Activities In Katmai National Park

The volcanoes in Katmai have created some interesting landscapes, and their activities have encouraged geologists to explore the possibilities.

Nonetheless, the Valley of Ten Thousand Smokes is the most prominent volcanic landscape in Katmai.  

It is the work of the largest volcanic eruption in the 20th century.

The Novarupta Volcano eruption on 6th June 1912 created this valley.  

There are various exciting destinations in the Valley of Ten Thousand Smokes.

For the geologists and people studying volcanoes, Novarupta is the ultimate destination.

The dome causing the massive eruption in 1912 still carries warm steam.  

It is also the most colorful place in the valley, thanks to its kaleidoscopic views caused by the deposition of ash, pumice, and other minerals.  

Another popular destination in the valley is the Buttress Range Ridge.

Here, you will catch a glimpse of the extensive wildlife in Katmai.

Along with the bears, you will also find ptarmigan, ground squirrels, and caribou.  

Other fascinating spots to explore in this valley are Katmai Pass, Southwest Trident Lava Flows, Knife Creek Glaciers, Mount Katmai Caldera, Mageik Lakes, etc.

Jetavanaramaya: Standing Before The Tallest Brick Stupa In Anuradhapura

BY  Sibashree Sep 18, 2026

Jetavanaramaya is in the Sacred City of Anuradhapura, one of Sri Lanka's UNESCO World Heritage Sites.  It is easily the most physically overwhelming structure I have seen anywhere on the island.   Can you believe that this stupa was built using 93.3 million baked mud bricks in 301 CE?  Even today, though the stupa is around half the height of the original stupa, it still impresses, with a towering height of 71 meters.   Furthermore, archaeologists think that a three-foot brick wall could be constructed between London and Edinburgh or New York City and Pittsburgh with these mud bricks.   However, Jetavanaramaya is not just about the imposing height.   It has a rich history and spiritual significance. Also, recent news has put it back in the global spotlight.  I will discuss all these aspects in this article, along with everything you need to plan the trip yourself.  Jetavanaramaya At A Glance  Detail Information Location Jetavana Monastery, Sacred City of Anuradhapura, North Central Province, Sri Lanka Built by King Mahasena (r. 273–301 CE) started the construction  It was completed by his son, Sirimeghavanna/ Maghavanna I Original height Approximately 122 metres  It is the tallest brick structure ever built. Current height Approximately 71 metres, after 12th-century restoration under King Parakramabahu I Bricks used An estimated 93.3 million baked bricks Global ranking (at completion) Third-largest man-made structure on Earth, after the two Great Pyramids of Giza Base area Roughly 233,000 m²  Relic enshrined Believed to be a fragment of a sash or belt worn by the Buddha. UNESCO status Part of the Sacred City of Anuradhapura, inscribed as a World Heritage Site in 1982 Nearest town Anuradhapura city centre, about 4–5 km away  A Recent Spotlight: Jetavanaramaya's 2026 Global Moment Jetavanaramaya does not need an introduction due to its architectural magnanimity or significance in Buddhism.   However, it has become a talking point once again with CNN Travel publishing a detailed feature recently.   In the February 2026 post, CNN Travel has described it as “massive megastructure built for eternity.”   Also, the same post places it alongside the Great Pyramids in terms of ancient engineering ambition.  The piece, reported from Anuradhapura itself, spent time with Godamune Pannaseeha, a senior archaeology officer who has spent years studying the site.  Also, it framed the stupa within the living pilgrimage culture that still surrounds it.  As I have seen it, there were pilgrims in white, monks chanting at dawn, rituals that have continued largely uninterrupted for more than 2,000 years.  The coverage was picked up widely across the US and international outlets in the weeks that followed.  Moreover, Sri Lankan media noted it as a rare moment of global attention for a site that, despite its scale, remains far less visited than Sigiriya Rock Fortress or the Temple of the Tooth.   If you are planning a Cultural Triangle trip in 2026, this is genuinely a good year to see it before the crowds catch up to the coverage.  The History Behind The Tallest Brick Stupa In The World Jetavanaramaya is a physical record of a religious dispute.   Understanding why it exists makes the visit land differently, even if we forget about the height or scale for a while.  King Mahasena And The Sect Rivalry That Built It  King Mahasena began construction of this stupa between 273 and 301 CE.  It was during a period of real tension between two Buddhist sects, the Mahavihara and the more liberal Abhayagiri fraternity.  Mahasena was a patron of the Abhayagiri fraternity.   The stupa became the centrepiece of the Jetavana Vihara, a monastic complex built for the breakaway Sagalika sect.  It was designed, according to archaeologists, to accommodate more than 3,000 monks.   Every structure in the complex was oriented toward the stupa.  It was a daily, physical reminder of where devotion was meant to point.  The Relic Enshrined Inside  Jetavanaramaya is a solid stupa, not a hollow one.  So, you cannot go inside.   What's believed to be enshrined at its core is a fragment of a sash or belt worn by the Buddha.  Thus, it is a cenotaph of deep religious significance rather than a burial monument in the ordinary sense.   Some accounts also connect the site to the cremation of Mahinda Thera, the monk credited with bringing Buddhism to Sri Lanka.  This version about the stupa comes from the excavated ash and charcoal layers found nearby.  Restoration Through The Centuries  Like most of Anuradhapura, Jetavanaramaya fell into decline after the capital shifted away from the city.  It was buried gradually by jungle growth and centuries of neglect.   King Parakramabahu I restored it in the 12th century, bringing it to roughly its current height.   Large-scale conservation further resumed in the 20th century, and it remains an active restoration site today.  Even in its diminished state, it is still the largest man-made brick structure by volume.  What It Is Really Like To Stand Before Jetavanaramaya Honestly, photos do not give a fair idea about the scale of the stupa.  Standing at its base, this is what I actually felt.   The Scale You Don't Expect  A height of 71 metres and made of 93 million bricks!  Reading about these numbers is different from actually walking the perimeter.   Each side of the base runs close to 576 feet, and the entrance staircases alone are around 28 feet wide.   It was a long walk circling the structure once.   However, the brick structure was more fascinating, with a distinct texture and color.   Furthermore, the uneven weathering of this deep terracotta structure is an art time has created.   No photograph truly captures that.   Golden Hour And The Rituals Around It  Afternoon is the best time to visit the stupa.   The heat is less, and the stupa looks warmer with a red-orange hue thanks to the light.   Also, this is the time when pilgrims in large numbers circumambulate the stupa clockwise.  They walk barefoot with flowers or lit oil lamps in their hands, and suddenly you see evening has set in.   Exploring The Jetavana Monastery Complex The stupa is the epicenter of the monastery complex.   However, if you want to know more about the history and soak in the spiritual ambiance, explore the other structures mindfully.   The Jetavanaramaya Museum  This on-site museum is small, but it displays artefacts recovered during excavation.  I saw beads, coins, ivory carvings, pottery, and inscribed stone fragments, along with information panels on the sect rivalry that produced the stupa.   It takes around 30 minutes to explore the museum. However, it is a useful stop, considering the information it provides.   Nearby Ruins Worth Your Time  There are remains of monastic buildings, ponds and boundary walls around the stupa.   The refectory ruins and stone urinals with their surprisingly intricate carved drainage systems especially demand a mention.  These structures hint at an organised monastic life.  Entrance Fees And Tickets Jetavanaramaya is covered by the single Anuradhapura Sacred City round ticket.  So, you do not need to buy a separate ticket for it.   Visitor category Approximate price (2026) Notes Foreign adult (non-SAARC) US$25–30 Covers:  Jetavanaramaya Ruwanwelisaya Abhayagiri Thuparamaya, and other sacred-city sites SAARC nationals US$12–15 Passport required at the counter Children (6–12) Around half the adult rate Under 6 generally free Local (Sri Lankan) visitors Free ID required and a small fee applies only for the site museums Combined Cultural Triangle ticket US$50–60 Covers:  Anuradhapura Polonnaruwa Sigiriya  Dambulla Royal Cave Temple   Note that the Sacred City round ticket does not include Isurumuniya, Sri Maha Bodhi, or Mihintale.  So, you will need smaller entry tickets.   You can buy tickets at the main office near the Archaeological Museum, or pre-book online to skip the queue.  Opening Hours And Best Time To Visit Jetavanaramaya The archaeological sites are generally open daily from around 7:00 AM to 6:00 PM.   Avoid the midday window (roughly 12:00–3:00 PM), when the heat over the open brick platform gets genuinely uncomfortable.   Early morning and the last two hours before closing are both good choices.  The latter also lines up with the evening rituals.   Moreover, December to March is the most pleasant season weather-wise, with lower humidity and less rain.  Getting There  Anuradhapura is roughly 200 km north of Colombo.  The journey takes around 4.5 hours by car.   Also, it is about 65 km from Dambulla.   Moreover, in a Cultural Triangle itinerary, it pairs naturally with Sigiriya, Dambulla, and Mihintale.   Again, since the Sacred City is vast, you can rent a bicycle for the day to move around.   The bicycle rental costs around LKR 1500 for a day.   Furthermore, you can hire tuk-tuks and cars with a driver-guide.  A Suggested Half-Day Itinerary For Jetavanaramaya  Time Stop What to expect 7:00 AM Sri Maha Bodhi Dawn pilgrimage atmosphere at the sacred fig tree. 8:00 AM Ruwanwelisaya The gleaming white stupa and its elephant wall. 9:15 AM Jetavanaramaya Spend at least an hour, and more with the museum. 10:45 AM Jetavanaramaya Museum Excavated artefacts and site context. 11:30 AM Abhayagiri Dagoba The third great stupa, with a quieter, more forested setting. 1:00 PM Lunch in Anuradhapura town Break before the afternoon heat.  Tips From My Visit To Jetavanaramaya A local guide (arranged through your hotel or the ticket office) adds real value here. You cannot know much of the sect rivalry from the on-site signage.  You can take photos here. However, avoid posing with your back to the stupa or in disrespectful positions.   This is an active religious site for Buddhist pilgrims.  Beyond Jetavanaramaya: Continuing Your Anuradhapura Journey Jetavanaramaya fits easily into an Anuradhapura itinerary, including Ruwanwelisaya and Mihintale.  This cluster is the best way to get a full picture of the ancient capital.  Furthermore, you can continue south from here to other major Buddhist sites such as Mulkirigala and Kataragama.  Why Jetavanaramaya Still Matters  The significance of Jetavanaramaya is specific.   It is proof of Sri Lankan excellence in craftsmanship in the fourth century.   Even then, they could organize labor and materials and execute an ambition on a scale that rivalled any civilization of that era.  So, around 1700 years later, when you stand at the base of the stupa, it is like time travel.

What To Pack For A Week-Long Camping Trip?

BY  Sibashree Jan 9, 2026

“Ma, will you miss me when I am in the camps and do the trek with my school friends?” I was a little surprised, as every mom would be when a 13-year-old these days says such emotional things! I looked at her and then straight at her rucksack and the entire mess around it.  She read my expression. “Ma, I don’t know what to pack for camping. My class teacher gave us a list, and I cannot find it now.”  There is no point in telling her that she cannot be so careless with plans of camping and trekking in her mind. I texted her teacher, and until she replied, I got started with the basics.  My years of experience as a traveler and travel writer were waiting for this day of glory 😉! Nevertheless, sometimes, being a mother, you have to do things! Now, a whole week of camping may sound amazing. Fresh air, quiet mornings, that forest smell that sticks to everything. Honestly, it’s like hitting the reset button.  Then reality hits. Seven days out there? What even do you bring?You want fun, not a trip full of “why did I leave that jacket at home?” or “Ugh, no power again.”So, what actually goes in your bag without turning it into a nightmare? Here are some practical tips you need to remember.  What To Pack For Camping? Things You Need To Carry For Survival  You need a good shelter, food that keeps you going, and some survival tools when you are camping. Also, keep some books or board games handy to spend those long evenings.  1. Shelter And Sleep Essentials A solid tent is a must. Rain, wind, surprise weather! Your tent better not bail on you. Some tents are super roomy but heavy. Your shoulders will hate you. If you’re hiking far, weight matters more than space. I had to spend 30 minutes convincing my daughter about the same and had to make her talk to my fellow trekker, whom she, of course, trusts more than me.  Now, it’s about the sleeping bag. You have to consider the weather and ground conditions when choosing the right one.  If the bag is made of synthetic material, it will help to manage wet weather. But, if you are choosing down bags, those will be more compressible and occupy less space. However, they will not forgive your wet conditions.  In addition, you have to carry sleeping pads. Sleep on the hard ground for two nights, and you will know why you need these sleeping pads.  Pillow, of course, is an optional choice. I made a makeshift pillow for my daughter by stuffing some old clothes in a bag.  2. Clothing Weather changes, and fast. Cold mornings. Hot afternoons. Damp nights. You get the idea. Layers that dry fast are your friend. Zip-off pants, light jackets, even a swimsuit, sound extra, I know. But there’s that one river crossing or random rainstorm where you’ll be glad.  Socks. Bring more than you think. Blisters ruin everything. Shoes matter too. Waterproof boots, yes. But a lighter pair for hanging around camp? Total win. 3. Food Freeze-dried meals are easy, lightweight, and actually tasty now. Add fruit, nuts, or some cooked food if you can. I got my daughter a few protein bars. I made those at home using roasted sesame seeds, jaggery, and peanuts.  Also, I stir-fried some boiled peas with salt and some seasoning and packed them in a zipper pack. These munchies really help, and unlike the ready-made snacks in the market, these don’t make you feel dehydrated.  Breakfast? Keep it simple. Oatmeal, instant coffee, snack bars. Done.Lunch is usually wraps, nut butter, and trail mix. Easy stuff. Dinner? One-pot meals are gold. Less cleanup, less stress. Don’t forget small things like oil, salt, or spices. Little stuff goes a long way.  Water. Super important. Bring enough. Know where to refill. Hiking miles because you misjudged water? No thanks. 4. Tools And Survival Necessities A good knife, a small multi-tool, and a headlamp with extra batteries, and you’ll use these more than half the fancy gadgets you’re tempted by. Use maps or a compass, even if you have a phone. Phones die. Signal disappears. Happens. Electronics? Charging them can be annoying. Also, portable energy solutions can save your sanity at some point, trust me. 5. Safety Essentials Hygiene. Boring, but trust me! After day three, you’ll care. Soap, toothbrush, wipes, quick-dry towel. Sunscreen and bug spray! You cannot forget any of these essentials.  You will also need a first-aid kit. Blisters, cuts, aches, all of it! Bring painkillers, allergy meds, and anything personal you need.  Hand sanitizer is more than just about germs. Whistle or signal tool? It might feel extra, but one day you’ll be glad you have it. 6. Entertainment Evenings can be long. Books, journals, cards, and small instruments will help you to pass the time. Hammocks are great for some chill instantly. You will love staring at trees or taking photos when relaxing in a hammock.  Also, you can bring camp chairs. Sometimes, comfort wins over minimalism, especially when you are doing back-to-back camping or trekking.  What To Pack For Camping? Don’t Feel Overwhelmed  Are you camping for the first time, and that too for seven days? The packing procedure can get a bit overwhelming.  It’s okay. However, making a list of essentials or talking to your tour operator will help. Also, you can reach out to anyone in your camping group. When traveling solo, you can post your queries in Facebook travel groups.  Still, it all starts with getting a good quality tent, and you have to learn how to set it up properly. Also, carry layered clothes as temperatures change and weather conditions can change dramatically after sundown, or there can be sudden turns of events.  Furthermore, you will need lights and lightsaver tools, and you must keep your meals simple.  Moreover, you have to keep some things or aspects spontaneous while camping. Everything will not happen as planned. You may have to collect a dead branch and wash it to use in cooking if you have left the spatula at home! Things like these will happen, and how you overcome them is the real fun of camping.

Exploring the Geothermal Wonders of Lassen Volcanic National Park

BY  Sibashree Aug 20, 2024

Lassen Volcanic National Park gets its name from the Lassen Peak, an active volcano in the southernmost Cascade Range. Even today, the Lassen Peak has hot springs and you will find fumaroles coming out of the peak’s mouth. These are also signs of volcanic activities in the volcanic mountains. Further, this national park houses all four types of volcanoes: plug domes, cinder cones, composites, and shields. These volcanoes make this national park a chosen destination for geologists and volcano enthusiasts. The presence of these volcanoes has also added unique hydrothermal features to this park. You will find vibrant hot springs, steam vents making hissing sounds, and mud pots with bubbling water here.  Here, I present a brief overview of the geothermal wonders of the park. I will also talk about the park’s camping provisions.  Geothermal Areas In Lassen Volcanic National Park The Lassen Volcanic National Park had 418,978 visitors in 2023, and we can say that its hydrothermal features are a major factor in crowd-pulling here. Snow falling on the park highlands and rainwater keep feeding the geothermal systems. Under the Lassen Peak, there is a molten or hot rock body. This hot rock body makes the water warm once it reaches underground. When the water becomes hot, you see the water boiling in the geothermal pools and mud pots. As the temperature of the water rises, it gets transformed into fumaroles. Fumaroles exude from various cracks in the earth. In Lassen Volcanic National Park, you will observe fumaroles at Sulphur Works, Devils Kitchen, and Bumpass Hell.  Little Hot Springs Valley You can have a look at the Little Hot Springs Valley from Lassen Peak (the largest plug demo volcano in the world) and other mountains lining it.   Further, various seasonal creeks drain into this valley, feeding the geothermal water. If you overlook the valley from the mountain peaks in the summer, you will see many wildflowers smiling. In particular, grass and the wildflower vegetation across the East Sulphur Creek edge is quite dense, thanks to various hypothermal activities. You can also look at the Little Hot Springs Valley from a pullout, just one mile away on the south. The view from this pullout is scenic, with lush green slopes before your eyes. If you look at the slopes with binoculars, you will find black bears roaming around.  Bumpass Hell https://www.youtube.com/watch?v=7OE_c2SzWNw As you walk 7 miles from the southwest entrance of the park, you will find a parking area on the park highway. Here, you will find the trail to Bumpass Hell. With a 3-mile hiking trail(round trip), Bumpass Hell is the largest geothermal area in the park. You can only hike the Bumpass Hell trail in autumn and summer. It remains closed during spring and winter. The temperature of the geothermal water in the Bumpass Hell area can reach up to 322 degrees.  The elevation of this trail is 8,000 feet. However, because of its moderate difficulty level, you will find many visitors here on weekends. The water in this hydrothermal area is emerald green or blue in color. Further, the minerals in the water stain the rocks and soil in yellow and orange shades.  Sulphur Works It can’t get easier than hiking to Sulphur Works if you want to explore the geothermal wonders of Lassen Volcanic National Park. Here, you can see how volcanic activities have created the most interesting geology with shifting new and ancient grounds.  The landscape here experiences regular updates because of geothermal activities and natural activities like erosion. Also, thanks to the volcanic activities, you will encounter colorful rocks, steam vents, and the most pungent sulphuric smell here. Sulphur Works is important in the Lassen Volcanic National Park history, and it was earlier known as Supan's Sulphur Works. Mathias B. Supan, a pioneer of the American West, used to extract minerals from the ground here in the mid-19th century.  https://www.youtube.com/watch?v=sTvAs6VPfIE The hydrothermal area of Sulphur Works is interesting as it is located at the center of a wide basin. Brokeoff Mountain, Mount Conard, Pilot Pinnacle, and Mount Diller surround this basin. According to geologists, these mountains are eroded formations or remains of Mount Tehama or Brokeoff Volcano. Boiling Springs Lake A trail starting from the Warner Valley trailhead will take you to the Boiling Springs Lake, filled with hot and bubbling water. The temperature of the water in this lake is 125 degrees.  You will also find steam vents and mud pots on the shore. The mud pots on the southeastern shore of the lake demand a special mention.  As you continue on the Boiling Springs Lake trail, you will see colorful wildflowers. The vegetation of Douglas-fir, sugar pine, incense-cedar, white pine, and ponderosa pine will soothe your eyes here. This trail is also a birder’s paradise and one of the best places in the park to observe birds.  Devils Kitchen https://www.youtube.com/watch?v=3Pah0QzBkN0 This hike, starting from the Warner Valley Trailhead, is moderate, and it will take you to an area filled with boiling pools, mud pots, and steam vents.
