Just 25 minutes from downtown New Braunfels — float crystal-clear, 72°F spring-fed water on a private, family-friendly stretch. No party scene, no chaos, unlimited floats all day.
Let's be honest — if you live in New Braunfels or you're visiting, you already know about tubing. The Comal, the Guadalupe, the Horseshoe Loop, the Schlitterbahn-area outfitters — you've probably done them all. They can be fun, but they can also be shoulder-to-shoulder packed, loud, and dominated by the spring-break / college-party scene. Sometimes you just want to actually relax on the river.
That's exactly why people from New Braunfels make the easy 25-minute drive northeast to Son's River Ranch. We're on the San Marcos River — a completely different, less-traveled river with crystal-clear, spring-fed 72°F water straight from the Edwards Aquifer. No dams. No chutes. No rapids. Just a calm, gentle current carrying you through a private 1.5-mile stretch of cypress-lined Hill Country.
For NB locals, this is the secret weekday escape — close enough to be a regular thing, but far enough that it's a true change of scenery from your home rivers. For visitors staying in New Braunfels, it's the family-friendly half-day trip that pairs perfectly with everything else you came here to do. Either way, it's tubing the way it should be: quiet, clean, and built around families, not party crowds.
We own both the put-in and the take-out, so our shuttle loops you right back to the start — tube as many times as you want all day for one flat price. No third-party drop-offs, no hour-long shuttle lines, no rushed one-way float. It's the calm Hill Country river day New Braunfels has been missing.
