Texas State Tubes
Texas State Tubes is one of the most popular outfitters on the San Marcos River. They offer both walk-up trips, where you drive to the launch point, and full-service packages that include transportation and tube rentals. The staff handles everything from shuttles to safety gear, so you can focus on enjoying your float. They also cater to groups, with private and corporate packages available, making it a favorite for large gatherings and special events.

Their tubing route runs through the downtown stretch of San Marcos and lasts about 45 minutes to an hour. It’s a quick, easygoing float that’s perfect for beginners or families. The best part is their unlimited shuttle service, which lets you float multiple times throughout the day for one flat rate.
Don’s Fish Camp
Located near Martindale, Don’s Fish Camp offers a fun and laid-back tubing experience outside the downtown area. Their float trips include parking, tube rentals, and a shuttle ride back to your car. The river here has a peaceful, scenic feel, and the camp itself often doubles as a hangout or overnight spot for groups. Many visitors enjoy camping out by the river after a day of floating, giving it a classic Texas summer vibe.
ZTX Ranch
For those looking for a quieter experience, ZTX Ranch provides private river access with on-site rentals and shuttle services. The private setup means fewer crowds and a more relaxed atmosphere.

Before heading out to the San Marcos River, a little planning goes a long way toward making your tubing day smooth and stress-free. From how long you’ll float to what it’ll cost, here’s what to know before you go.
Duration: How Long the Float Takes
Most tubing trips on the San Marcos River last between one to four hours, depending on where you start and which outfitter you choose. Shorter floats, like the downtown route offered by Lions Club Tube Rental, take about 45 minutes to an hour—perfect for a quick dip or family outing. Longer routes, like those from Texas State Tubes or Don’s Fish Camp, can stretch to three or four hours, letting you relax and soak up the scenery. If you want to take it slow, pack snacks and drinks so you can float at your own pace.
Pricing: What to Expect
Prices vary depending on the outfitter, the day of the week, and whether you bring your own tube. Expect to pay around $20 to $30 per person for a full package that includes tube rental and shuttle service. If you bring your own tube, some outfitters offer discounted shuttle-only rates, which can save you a few dollars. Many places also have group discounts or weekday specials, so it’s worth checking before you go.
Logistics: Getting There and Getting Back
Most outfitters provide free parking at their lots and a shuttle service that takes you to the launch point and picks you up at the end of your float. This makes the day easy—you park once, and they handle the rest. For the downtown float, you can park near City Park and use the Lions Club shuttle to loop back as many times as you’d like. For longer floats like those in Martindale, it’s best to check the shuttle schedules to make sure you catch the last ride of the day.
Bringing cash or a card is helpful, as many outfitters rent extras like coolers, ice chests, or waterproof bags. It’s also smart to arrive early, especially on weekends, since parking lots fill up fast. For a change of scenery, check out Guadalupe River State Park, where adult entry is $7 and kids under 12 are free.
With a little preparation, your San Marcos River tubing adventure can be as relaxing or adventurous as you want it to be. Plan ahead, pack right, and you’ll be ready for an unforgettable day floating down one of Texas’s most beautiful rivers.
Year-Round Activities Beyond Summer Tubing
Although summer draws the biggest crowds, the San Marcos River offers enjoyable activities in all seasons. Thanks to its stable temperature, you’ll find excellent options year-round with outfitters like Texas State Tubes. Just like the Comal River, the San Marcos remains a top choice thanks to its steady 72°F waters.
Kayaking and Paddleboarding
When tubing season slows down, kayaking and paddleboarding take over. The river’s clear, calm flow makes it ideal for both beginners and experienced paddlers. You can rent gear locally and explore at your own pace, gliding through peaceful stretches shaded by cypress trees. It’s a great way to enjoy the river without the summer crowds.
Fishing and Wildlife Watching
The San Marcos River is home to a variety of fish, turtles, and birds, making it a relaxing spot for catch-and-release fishing or simply soaking up nature. Anglers often come for perch, bass, and catfish, while birdwatchers keep an eye out for herons, kingfishers, and other native species. Cooler weather brings calmer waters, perfect for quiet mornings on the riverbank.
Hiking and Riverside Picnics
Surrounding parks like Sewell Park and Rio Vista Park offer beautiful trails, shaded picnic areas, and open green spaces to enjoy year-round. Fall and spring are especially nice for walking or biking nearby paths, as temperatures are mild and the scenery is vibrant.
Local Events and Downtown Fun
The city of San Marcos keeps the energy going even when tubing season winds down. You’ll find festivals, live music, and outdoor markets throughout the year, especially around the square and university area. Many visitors pair their river visit with a stop downtown for great food, local art, and shopping.
Winter and Spring Adventures
Even in winter, the San Marcos River doesn’t lose its charm. Because the water stays warm, you’ll often see people snorkeling, diving, or kayaking even on chilly days. Springtime brings wildflowers along the riverbanks, giving the area a fresh, colorful look that’s perfect for photos and leisurely strolls.
Safety Tips and River Etiquette for First-Time Tubers
A successful tubing trip starts with knowing basic safety rules and practicing good river etiquette.
Safety First
-
Wear a life jacket if you’re not a strong swimmer or if you’re tubing with kids. Even though the river is calm, currents can vary in some areas.
-
Stay hydrated—Texas heat can sneak up on you, especially when you’re out for several hours. Bring plenty of water.
-
Avoid glass containers. Many river areas ban them for safety reasons, so stick with cans or plastic.
-
Protect yourself from the sun. Apply waterproof sunscreen, wear a hat and sunglasses, and take breaks in the shade if possible.
-
Watch for obstacles. Keep an eye out for rocks, low branches, and other tubers to avoid collisions.
River Etiquette
-
Respect the environment. Don’t litter—use the provided trash bags or bring your own to pack out what you bring in.
-
Be courteous to others. Keep your music at a reasonable volume, and give other floaters space to enjoy their day too.
-
Follow local rules. Each outfitter and section of the river may have its own regulations, so take a minute to review them before launching.
-
Stay with your group. It’s easy to drift apart on the water, so tie tubes together or set a meeting point if someone floats ahead.
-
Leave wildlife alone. The river is home to fish, turtles, and birds—observe them, but don’t disturb them.
