If you've spent a summer in Austin, you already know the drill: 100° heat, every public swimming hole packed by 10 a.m., and the Comal River in New Braunfels turning into a floating block party by noon. There's a quieter, cleaner answer for tubing near Austin, and it's a 45-minute drive south on I-35.
What makes the San Marcos River different
Unlike the Colorado below Austin or the Pedernales out west, the San Marcos is spring-fed — water bubbles up from the Edwards Aquifer at a constant 72°F and flows clear past Son's River Ranch. We sit on a private 168-acre stretch with small rapids and no dams, which means a gentle, scenic float without the crowds you'll find on the Comal or Guadalupe in New Braunfels.
How tubing works at Son's River Ranch
Buy an Ultimate River Fun Wristband at the property and float as many laps as you want. The shuttle handles the walk back. If you're staying overnight, that wristband stacks with 25% off other day rentals.

Is it safe for kids?
Yes. Our stretch is calm enough for first-timers but interesting enough that older kids and adults don't get bored. Life jackets are available, and there are wide shallow areas where younger kids can wade. For more, check the National Weather Service South Texas forecast before you head out.
Make a weekend of it
Pair tubing with a riverside cabana for shade and a grill, or stretch the trip into an overnight in a glamping cabin or safari cabin. The Tubing Near Austin landing page has the full breakdown of routes and pricing.
Heading toward Boerne instead?
Our sister property Son's Blue River Camp on the Blanco River is a great alternative if you're west of Austin — same family-run vibe, different watershed.

Reserve your wristband or cabana — peak summer weekends sell out.
