Idaho is the only western state that does not have a national park. However, some parts of the Yellowstone National Park, a UNESCO World Heritage Site, are in Idaho. Yellowstone National Park has witnessed a boost in the number of visitors in 2025. Furthermore, it has been recently in the news for how AI audio recorders are documenting bird chirps and wolf barks. Furthermore, while we can call Yellowstone the only and the best national park in Idaho, the state also has some state parks, national reserve, national monument, and national preserve. So, if you are looking for the best national parks in Idaho, you can visit these places. What Are The Best National Parks In Idaho? You can start your exploration of the best national parks in Idaho with Yellowstone National Park, as I have mentioned. Then, you will also love the Farragut State Park, City of Rocks National Reserve, and other outdoor gems in Idaho. 1. Yellowstone National Park The geology and the wildlife of the Yellowstone National Park are fascinating. However, only 1% of this magnificent national park is in Idaho. Furthermore, the UNESCO World Heritage Convention says, “Yellowstone contains half of all the world's known geothermal features, with more than 10,000 examples. It also has the world's largest concentration of geysers (more than 300 geysers, or two-thirds of all those on the planet). Established in 1872, Yellowstone is equally known for its wildlife, such as grizzly bears, wolves, bison, and wapitis.” So, it is no wonder that the Yellowstone National Park is at the epicenter of the “Greater Yellowstone Ecosystem,” (GYE) that stretches over 7 million hectares. In addition, you will find fossil plants of around 150 species here. Moreover, it has the largest recognized caldera in the world. Yellowstone National Park Now The Yellowstone National Park has witnessed a surge in its visitor numbers in 2025. According to the latest data from the National Park Service, 4,762,988 people visited this national park in 2025. It has secured the third position among the most-visited national parks in the USA. However, the Great Smoky Mountains National Park and Zion National Park, with 11,527,939 and 4,984,525 visits respectively, are the most and second-most-visited national parks in the USA. Furthermore, the Yellowstone National Park now has the “Cry Wolf” Project. It is a collaboration of the Yellowstone Wolf Project and Jeff Reed, a computational linguist. With this project, 50 recording units have been installed across 50000 acres of the park. These AI sound recorders record “Yellowstone's wolves as they bark, yip, howl, and whine.” Wolves have always been one of the most difficult animals to monitor. Thanks to this recorder, the problem of monitoring them has been solved here. 2. Craters Of The Moon National Monument And Preserve From one geological wonder to another! Craters of the Moon National Monument and Preserve has one of the most unique landscapes in the United States. What’s more fascinating is that the landscape is formed due to volcanic activities occurring over the last 15000 years. So, today, you will notice cinder cones, lava fields, and even “underground lava tubes” in this 753000-acre preserve. Furthermore, it gets its name from its unique terrain that looks like a lunar surface. Also, did you know that back in the 1960s, astronauts used to prepare for their lunar missions here? In addition, this national preserve is home to a wide range of wildlife, including: Pika Proghorn Mountain Lions Packrats Moreover, this national preserve with a volcanic landscape looks the most beautiful in the spring season. In the spring season, you will notice a wide range of wildflowers blooming on the dark rock. Again, the Craters Of The Moon National Monument and Preserve is one of the five designated dark skies in the state of Idaho. So, it is great for stargazing, and it is one of the best places to see the Northern lights in the USA. How To Explore The Craters Of The Moon National Monument And Preserve You can take the seven-mile Loop Road to get easy access to the trails of the preserve. Hike through these trails to explore the unique geological features like the Inferno Cone and Big Craters. Moreover, here you can see many lava tube caves. However, you will need a flashlight and, most importantly, a free permit to explore the caves. Furthermore, you can camp in the grounds of the Craters of the Moon, and don’t miss the exhibits on the geological forces at work here. Having said that, please keep in mind that the caves are now closed here due to snow and ice. They have been closed since 11/13/2025 and will remain closed till June 2026. 3.

It has the “tallest single-structured sand dune in North America.” The dune has a height of 470 feet, and it is a telltale of how wind and erosion have created a gorgeous landscape at the Bruneau Dunes State Park. Furthermore, the landscape, which is a work of the natural forces over 1000 years, is a sharp contrast against the mountainous region of Idaho. You will find the most popular trails in the park near the dunes, and while exploring them, you can spot wildlife such as mule deer, owls, and lizards.

Bruneau Dunes State Park’s astronomy programs are vital for raising awareness about protecting natural darkness from artificial light at night. Programs are offered to the public each weekend, attracting visitors with stunning celestial views and educational content, emphasizing dark sky conservation.
