River tubing isn't just for college kids and bachelor parties. Some of the best memories your family will ever make happen on a lazy Texas river. Your kids squealing through the tube chute, spotting turtles sunning on logs, and eating PB&Js on a sandbar. Central Texas has several family-friendly rivers within an hour of Austin, and with a little planning, even toddlers can join the fun. Here's everything you need to know to plan the perfect family float.
Best Rivers for Families
Not all rivers are created equal when it comes to floating with kids. Here's our breakdown:
🏆 #1 Pick: Comal River (New Braunfels)
The Comal River is the gold standard for family tubing. It's short (2.5-3 hours), shallow (2-4 feet most of the way), and gentle enough that little ones feel safe. The highlight? The tube chute, a concrete channel that speeds you up for a thrilling 30-second ride. Kids. Love. It. After the float, Landa Park has playgrounds, a spring-fed pool, and picnic areas. It's a full-day family destination, not just a tube trip.
🥈 #2 Pick: San Marcos River
The San Marcos River is spring-fed at a constant 72°F, crystal clear, and gentle. The 3-4 hour float is a bit longer than the Comal, so it's better for families with kids 7+. There are sandy spots to stop and play, and the water clarity means kids can watch fish swim underneath their tubes. It's also the closest river to Austin (45 minutes).
⚠️ Guadalupe River — Older Kids Only (10+)
The Guadalupe River is longer (4-5 hours), deeper in spots, and can have faster currents depending on dam releases. It's a fantastic river, but we only recommend it for families with kids 10 and older who are comfortable swimmers. Check river flow levels before booking.
Age Minimums & Life Jacket Laws
This is the most important section for parents. Know the rules before you go:
- Comal River: No children under 5 allowed on the river (New Braunfels city ordinance). This is actively enforced.
- San Marcos River: No hard age minimum, but most outfitters recommend age 6 and up.
- Guadalupe River: Recommended for kids 10 and older due to length, depth, and currents.
- Texas law: All children under 13 must wear a U.S. Coast Guard-approved life jacket at all times on any waterway, per Texas Parks & Wildlife regulations. No exceptions. Adults are encouraged to wear one too.
For complete river regulations, see our River Rules & Regulations guide.
Tips for Toddlers & Young Kids
Floating with kids ages 5–8 requires a little extra planning. Here's what experienced river families recommend:
- Young kids ride with a parent. One adult per child in the same tube or a double tube. Don't let kids under 8 float alone.
- Start early. Hit the river by 10 AM. Afternoon sun is brutal, and kids fatigue faster in the heat.
- Choose the shorter float. The Comal's 2.5-3 hour float is the perfect length. Four-plus hours on the Guadalupe is too long for young kids.
- Bring a "bail out" plan. On the Comal, there are exit points along the way if a child gets tired or upset. Know where they are before you launch.
- Apply sunscreen liberally. Kids burn fast on the water. Apply SPF 50+ before the float and bring a reapplication stick for halfway through.
- Pack twice the snacks you think you need. Hungry kids on the river = meltdown. Bring granola bars, fruit pouches, goldfish crackers — anything easy and waterproof.
Family Packing List
Here's what to pack for a family float trip. For the full detailed checklist, see our What to Bring Tubing guide.
Family Float Essentials
- Life jackets (outfitters usually provide them, but bring your own for toddlers/small kids)
- SPF 50+ sunscreen, waterproof, reef-safe preferred
- Water shoes for everyone, NOT flip-flops (rocky river bottoms)
- Snacks: granola bars, fruit, crackers, squeezable applesauce
- Water bottles, at least one per person, frozen works great
- Extra towels, more than you think you need
- Change of clothes for everyone including socks and shoes
- First aid kit: band-aids, antiseptic wipes, children's Benadryl
- Waterproof phone case for photos, or keep phones in the car
- Hats and sunglasses with straps so they don't float away
- Waterproof dry bag for wallets, keys, extra clothes
Guided Outfitter Trip vs. DIY
Families have two options: book with an outfitter or do it yourself. Here's how they compare:
| Guided Outfitter Trip | DIY (Bring Your Own Tubes) | |
|---|---|---|
| Tubes | Included | Bring or rent separately |
| Shuttle | Included (bus to/from river) | You need two cars or Uber back |
| Cost | $25-$55/person (all-inclusive) | Free + tube cost ($10-$20) |
| Stress Level | Low, everything handled | Higher, logistics on you |
| Best For | First-timers, large groups, families | Experienced locals, small groups |
Our recommendation for families: book with an outfitter, especially your first time. When you're wrangling kids, sunscreen, snacks, and life jackets, the last thing you want to worry about is shuttle logistics. See How It Works for a step-by-step walkthrough.
Making It Fun for Kids
A little creativity goes a long way on the river. Here's how to turn a good float into an unforgettable adventure:
- River scavenger hunt. Spot a turtle, a blue heron, a fish jumping, a dragonfly, a cypress knee. First kid to find all five gets to pick the restaurant for dinner.
- Waterproof camera. Give your kid a cheap waterproof camera or GoPro. They'll take 400 photos and 3 of them will be incredible.
- Fun river snacks. Frozen grapes, gummy bears, fruit roll-ups, anything that feels like a treat. Pack them in a ziplock in the cooler.
- River songs. Start a round of "Row, Row, Row Your Boat" when the current picks up. Corny? Absolutely. Memorable? Also absolutely.
- Sand bar stops. When you hit a shallow sand bar, hop out and let the kids wade, splash, and skip rocks. These unplanned breaks are where the magic happens.
