BY Sibashree Feb 9, 2023
Like many visitors, I almost missed San Marcos. It is a stop on I-35, and it is easy to drive past it on the way between Austin and San Antonio. However, every time I am in Texas, I plan a day around it. I love the spring-fed river, the century-old cave, and the honky-tonk that launched a country legend. So, in this article, I will talk about the things to do in San Marcos along with some other details. San Marcos At A Glance DetailWhat to knowLocationRoughly 30 miles south of Austin and 40 miles north of San Antonio (San Marcos Chamber)River temperatureAbout 72°F year-round (Visit San Marcos)Glass-bottom boat$12 adults, $10 seniors, and $8 children 3–12Lions Club tubing$25 per tube with unlimited shuttle Outlet shopping200+ stores, and they have about 14 million visitors a year.2025 visitor spending$208.7 million, supporting about 2,600 local jobs (Visit San Marcos, May 2026). What’s New In San Marcos And Worth Knowing For 2027? If you are planning around the springs 2027, you need to know two updates. The Meadows Center has scheduled maintenance closures on January 11–15, 2027, and August 18, 2027. Since February 2026, day parking permits bought at the kiosk carry a 10% service fee, So, you must use the AMP Park app instead. Wonder World Cave and Adventure Park is scaling back its schedule. Its homepage currently advertises opening on Fridays and weekends, so book a tour time before driving out. If you like spectacle, the Texas Water Safari is worth timing a trip around. The 260-mile canoe race begins on the second Saturday of June. In 2027, that is June 12, weather permitting. Confirm with the organizers. Best Things To Do In San Marcos With Kids Kids do best in San Marcos when the day mixes water, animals, and something a little strange. These are the three activities you must try with them. Meadows Center Glass-Bottom Boat Tour This is the first thing I book. The 30-minute tour of Spring Lake shows the lakebed, plants, animals, and the springs themselves through a glass panel. The boats are a piece of local history, since they’ve been running since 1945. The lake is an ecological treasure. It holds eight federally listed endangered or threatened species. Grounds access is free and includes a self-guided wetlands boardwalk. Also, the on-site aquarium has free admission. Note that winter hours run 9:30 a.m. to 4:00 p.m. and the last boat leaves 30 minutes before closing. Wonder World Cave And Adventure Park Wonder World is a ready-made family half-day. The guided cave tour visits the nation’s only true earthquake-formed cave. Above ground, you get the Anti-Gravity House, a train ride, and a petting park with deer and goats. However, strollers are not allowed on tours, and the cave and Anti-Gravity House are not wheelchair accessible. River Tubing For Beginners For young kids, I would pick the Lions Club float over the longer trips. It takes about 45 minutes to an hour, versus about three hours with Texas State Tubes or Don’s Fish Camp. Here’s how the three compare. OutfitterCostFloat lengthLions Club Tube Rental$25/tube and $15 for shuttle if you bring your own.About 1 hourTexas State Tubes$30 rental and $10 for ages 7–12Free for 6 and under (life jackets required)About 3 hoursDon’s Fish Camp$30, or $19 with your own tubeAbout 3 hours Safety matters here because there are no lifeguards on duty. Put life jackets on non-swimmers. Discovering the Mermaid Art Trail San Marcos proudly celebrates its title as the Mermaid Capital of Texas through a whimsical, city-wide public art project. Keep an eye out for the Mermaid March, a trail of ten 7-foot-tall fiberglass mermaid statues scattered across the city. Each statue is individually hand-painted by a local artist to showcase different aspects of San Marcos's history, culture, and environmental preservation efforts. It makes for a fantastic, free scavenger hunt. It also bridges the gap between downtown shopping and the river, offering perfect photo backdrops while highlighting the community’s deep creative roots and love for its pristine waters. Best Things To Do In San Marcos For Adults Adults get the same river, plus music and shopping that make an evening out of it. Cheatham Street Warehouse If you love Texas music, this is the pilgrimage. Kent Finlay and Jim Cunningham opened the club in June 1974. George Strait’s band played its first show there on October 13, 1975. The venue is now overseen by country star Randy Rogers and still hosts weekly songwriter circles. I’d check the calendar and pair a show with dinner downtown. Paddle Or Snorkel Spring Lake For something quieter than tubing, the Meadows Center offers guided kayak and SUP tours, limited to paddlers aged 12 and up. Because the lake is so protected, this is among the few chances to be on the water at the springs’ source. The Outlets The adjacent Tanger Outlets and San Marcos Premium Outlets are consistently ranked among the state’s most popular tourist attractions. I go on weekday mornings to skip the crowds.

Visit it early in the day as tubing crowds become dense by mid-morning. Also, the boats and caves are calmer before noon. Also, reserve ahead for Wonder World and the boats on weekends and holidays. Furthermore, check the dates of big events such as the Water Safari and holiday weekends push up demand. Also, budget for parking, especially if you are visiting the Meadows Center. Is San Marcos Worth It In 2027? Yes, a visit to San Marcos is worth it in 2027. Tourism is a real economic engine here. The 2025 visitor spending reached $208.7 million and supported about 2,600 jobs. The town has also earned its identity, since the Texas legislature named it the Mermaid Capital of Texas in 2021. So, come for the water, and stay for the music.
