Is Son's Blue River Camp the same as the Comal or Guadalupe tubing scene?

No. We're on a quieter, family-friendly stretch of the spring-fed San Marcos River in Kingsbury, TX — not the Comal or Guadalupe party rivers. We cap day-pass numbers, don't allow public outfitter drop-offs, and the property is 8 private acres rather than open public access.

How far is Son's Blue River Camp from Austin, San Antonio, and Houston?

About 45 minutes from Austin and San Antonio, 25 minutes from New Braunfels, and roughly 2.5 hours from Houston.

Is the San Marcos River safe for kids and beginners?

Yes. Our 1.5-mile stretch is gentle, spring-fed, and shaded by cypress trees — well suited to families, first-time floaters, and kids in life jackets. Lifeguards aren't on duty, so children should be supervised at all times.

Are pets allowed at Son's Blue River Camp?

Son's Blue River Camp is pet-free to keep the property quiet and family-friendly. Service animals are welcome.
