Private cabanas, tubing, and kayaking in the Texas Hill Country. Shaded shoreline, clean shower trailers, and a spring-fed river — all just a few hours from Austin, Houston, and San Antonio.
Three ways to enjoy a daycation on the San Marcos River
The San Marcos River is spring-fed, flowing cool and clear all summer long, even in the harshest of droughts. Enjoy a gentle, relaxing float through beautiful cypress and pecan trees. Perfect for all ages. Tube or kayak as many times as you want with our unlimited wristband, and our friendly shuttles bring you right back to do it again.
Room to spread out. Your family won't feel packed in like sardines.
Float 1.5 miles without bumping into strangers. This isn't downtown New Braunfels.
AC cabins, clean bathrooms, shaded spots. Glamping means no suffering.
No rowdy party crowds. Just family and friend groups who respect each other.
Transparent pricing. Your cabin & cabana comes with grill, hammock, seating — no nickel-and-diming.
We own the put-in AND take-out. Hop on a tube or kayak and we'll handle the rest.

Son's Blue River Camp is a family-owned, 8-acre riverfront resort in Martindale, Texas — just 90 minutes from Austin and San Antonio, and an easy drive from Houston. Spend the day lounging in a private riverside cabana, floating the spring-fed 72°F river, kayaking through clear Hill Country water, or grilling out at your own shaded picnic spot. With unlimited tubing and shuttle service, clean shower trailers, and welcoming family staff, it's the easiest way to escape the city without packing for an overnight stay.
Our day rental cabanas and picnic tables include river access, BBQ grills, and covered seating for up to 15 guests — perfect for birthdays, family reunions, church groups, and corporate outings.

Kids 3 and under are free, the river never runs dry, and the spring-fed water stays refreshingly cool even in the heat of summer.
Want to extend your day into a full Hill Country getaway? Our glamping cabins, log cabins, and bell tents let you wake up steps from the water with all the comforts of home — air conditioning, real beds, fire pits, and full kitchens in select units.
