The Ultimate Texas Tubing Guide

The Internet's Most Comprehensive Tubing Resource

Texas river tubing is how Central Texas gets through July— floating spring-fed water with friends and a cooler tube tied alongside. Every summer, millions of Texans and visitors descend on the Hill Country's rivers for lazy floats that can last anywhere from 45 minutes to four hours. With a dozen-plus rivers and dozens of outfitters, picking one for a big group is the hard part. Which river fits your crew? What are the can rules? What does it cost? We drive tubing groups down I-35 most summer weekends, so here is what we tell them: every major river, the outfitters with prices and phone numbers, the rules in each town, what to bring and what to leave at home, and how the day actually goes when twenty people do it together.

Top Rivers for Tubing: A Detailed Breakdown

San Marcos River — Fed by over 200 springs at the headwaters in San Marcos, this river maintains a constant 72°F year-round. The typical tubing stretch runs about 3 miles from City Park to Rio Vista Falls (or beyond to Martindale), with float times of 1.5–3 hours depending on flow. Difficulty: easy to moderate. The river bottom is visible in most sections thanks to exceptional clarity. You'll float through town past Texas State University, over gentle riffles, and through a few fun chutes. Rio Vista Falls provides a mild rapid that adds excitement without danger. Best for: beginners, families, and college groups who want clear water and a lively atmosphere.

Comal River — At just 2.5 miles, the Comal holds the title of the shortest navigable river in Texas (and one of the shortest in the world). It's 100% spring-fed from Comal Springs in Landa Park, New Braunfels, keeping the water a steady 70–72°F. Float time: 45 minutes to 2 hours. Difficulty: easy — there's a gentle current the entire way with one fun tube chute near the end. The Comal is ideal for a shorter, more relaxed float. Scenery includes towering cypress trees, residential backyards, and Landa Park's manicured grounds. Best for: first-timers, shorter outings, and groups who want to combine tubing with exploring New Braunfels or Gruene.

Guadalupe River — The most popular tubing river in Texas, flowing through the Guadalupe River State Park area, New Braunfels, and Gruene. The main tubing stretch from above Canyon Lake dam to New Braunfels covers roughly 6–11 miles depending on your put-in and take-out points, with float times of 2–4+ hours. Difficulty: easy to moderate — some sections have faster currents and small rapids, especially below the Canyon Lake dam during releases. Water temperature varies: 65–75°F depending on dam releases. The scenery is classic Texas Hill Country — limestone bluffs, bald cypress, and occasional rope swings. Best for: groups who want a longer float, more of an adventure, and the quintessential Texas tubing experience.

Frio River — Located about 2.5 hours southwest of Austin near Concan and Garner State Park, the Frio ("cold" in Spanish) lives up to its name with spring-fed temperatures around 68°F. The typical float stretch is 3–5 miles with a float time of 2–4 hours. Difficulty: easy to moderate, flow-dependent. The Frio is arguably the most scenic tubing river in Texas — towering limestone cliffs, crystal-clear emerald water, and virtually no development along the banks. Best for: groups who want a weekend getaway, camping, and a more remote, nature-immersive experience. The drive is long enough that most groups we take to the Frio sleep the whole way home on the party bus — nobody wants to be behind the wheel for 2.5 hours after a day of sun.

Blanco River — A quieter alternative running through Wimberley and the town of Blanco. Float stretches are 2–4 miles with times of 1.5–3 hours. Difficulty: easy, highly flow-dependent. Less commercial than the Guadalupe or Comal, the Blanco offers a peaceful, uncrowded experience when water levels cooperate. Best for: groups who want to avoid crowds and combine tubing with a visit to Wimberley's shops, galleries, and Blue Hole.

Barton Creek — Right in Austin, Barton Creek flows through the Greenbelt with swimming holes like Sculpture Falls and Twin Falls. Tubing is possible but extremely flow-dependent — it's only floatable after significant rain. No commercial outfitters. Best for: spontaneous local floats when conditions align. Check flow levels at USGS Barton Creek gauge before going.

Outfitters shuttle you between put-in and take-out, but they don't get you there from Austin. That's the part a party buscovers: one pickup in town, a ride down I-35 with the cooler already open, a drop at the outfitter's door, and a bus waiting in the lot when you climb out — so nobody has to stay dry for the drive home.

Rules & Regulations by Location

Each river and city has its own rules, and they're enforced — fines can reach $500+. Know before you go:

New Braunfels (Comal & Guadalupe): Disposable containers (Styrofoam coolers, single-use plastic cups) are banned on both rivers. Containers must be reusable and have a secure lid. Coolers must be 30 quarts or smaller. No glass anywhere on the river. No cans larger than 16 oz. You can bring alcohol in approved containers. Life jackets are required for children under 6 and strongly recommended for all. The city actively patrols during summer. Visit nbtexas.org for the full ordinance.

San Marcos:Rules are more relaxed. Cans are allowed. No glass. Styrofoam is banned. No littering (obviously). Alcohol is permitted on the river, but public intoxication laws apply once you're on land. Life jackets recommended for all; required for children under 6.

Frio River: Rules vary by property owner and county. Generally: no glass, pack out all trash, respect private property along the banks. Alcohol is permitted in most areas. Garner State Park has its own rules — check with park rangers.

Universal rules everywhere:Leave no trace. Don't litter — fines are steep and it ruins the rivers for everyone. Stay off private property. Don't jump from bridges or structures unless posted as safe. Respect wildlife — you're in their home.

Best Time of Year & River Flow Conditions

Texas tubing season generally runs May through September, with peak season being Memorial Day through Labor Day. Water temperatures are most comfortable June–August. The spring-fed rivers (San Marcos, Comal) are floatable year-round since their temperature and flow are constant, though outfitters only operate seasonally.

River flow is measured in cubic feet per second (CFS) and dramatically affects your experience. For tubing, you generally want:

Ideal range:100–300 CFS for most rivers. At this level, the current is steady enough to carry you without effort, the water is deep enough to avoid scraping bottom, and it's safe for all skill levels.

Low flow (<60 CFS): You may scrape bottom, get stuck on rocks, and spend more time walking than floating. Not ideal. The Guadalupe and Blanco are especially affected — without dam releases or recent rain, they can become too shallow.

High flow (>500 CFS): Rivers can become dangerous. Currents are strong, obstacles are harder to avoid, and the water turns murky. Most outfitters will close when flow exceeds safe levels. Never tube on a flooded river.

Check real-time conditions at USGS Texas Water Data before every trip. Key gauges to bookmark: San Marcos at San Marcos (08170500), Comal at New Braunfels (08169000), Guadalupe at New Braunfels (08168500).

What to Bring

Sunscreen: Waterproof, SPF 50+. Reapply every 90 minutes. You're on the water for hours with no shade — sunburn is the biggest regret of first-time tubers. Water shoes or sport sandals: River bottoms are rocky. Flip-flops float away. Chacos, Tevas, or old sneakers work best. Reusable cooler: Hard-sided, 30 quarts or smaller (required in New Braunfels). Fill with ice, water, and beverages in cans. Dry bag: For your phone, keys, and wallet. Get one that clips to your tube or shorts. Water bottle: Dehydration is real — alternate between fun drinks and actual water. Hat with a chin strap: Regular caps blow off on the river. Rash guard or lightweight long-sleeve shirt: Superior sun protection versus sunscreen alone. Rope or carabiner: To tie tubes and cooler tubes together for group floats.

What NOT to Bring

Glass — anything glass. Banned on every river and a safety hazard. Styrofoam coolers: Banned in New Braunfels and San Marcos. They break apart and litter the river. Expensive jewelry or electronics: If it goes in the river, it's gone. Inflatable pool toys: They pop on rocks and become trash. Use proper river tubes from outfitters. Excessive amounts of stuff:You're floating, not glamping. Keep it simple — the less you bring, the less you have to keep track of.

Group Tubing Tips

Tie together:Use 10–15 feet of rope to loosely connect tubes. Don't tie too tight — you need slack for navigating around obstacles. Designate one or two "cooler captains" who manage the drink tubes.

Set a pace leader: Put your most experienced tuber at the front to scout the route and call out any hazards. The group follows their lead.

Know your exit point: Every outfitter will tell you where to get out. Missing your exit means either a long walk back or floating into areas that may not be safe. Pay attention to landmarks.

Big groups: With ten or more, call the outfitter ahead — some have group rates, and they'll tell you when to show up. Arriving on one party bus instead of a five-car caravan means nobody gets lost on FM 306 and nobody has to be the DD.

Safety: Hydration, Sun & Alcohol

Hydration:You're losing water through sweat, sun exposure, and (if applicable) alcohol consumption. Drink at least one bottle of water per hour. Dehydration leads to dizziness, cramps, and heat exhaustion — all dangerous when you're on the water.

Sun protection:Texas summer sun is relentless. Apply sunscreen before you get on the river, and bring the bottle to reapply. Wear a hat. A rash guard is worth it even if you think you don't burn — reflection off the water doubles your UV exposure.

Alcohol: Drinking on the river is legal in most areas (see rules above), but public intoxication laws still apply. More importantly, impaired judgment on moving water is dangerous. Pace yourself. Eat before and during your float. And nobody drives after a float — that is the whole reason groups book a river float trip with a bus. The ride home from New Braunfels or San Marcos is when everyone falls asleep, and the driver is the one person who spent the day on land.

Life jackets:Required by law for children under 6 on all Texas waterways. Strongly recommended for anyone who isn't a confident swimmer. Most outfitters include them free of charge — there's no reason not to wear one.

Plan Your Float with Austin Party Ride

We drive tubing groups to the San Marcos, Guadalupe, Comal, and Frio every summer. Our party buses pick you up anywhere in Austin — homes, hotels, Airbnbs — and take you straight to the outfitter's door. While you float, we wait. When you're done, toweled off, and ready, we drive you back to Austin. The bus has a wet bar, coolers, a sound system, and LED lighting, so the day starts on the ride down and keeps going after. We serve New Braunfels, San Marcos, Gruene, Wimberley, and everywhere in between. Check our pricing guide and browse the fleet.
