Everything Son's River Ranch Offers for a Day on the Water
Son's River Ranch is a 150-acre, family-owned river resort on the spring-fed San Marcos River in the Texas Hill Country. The water stays a steady 72°F year-round, the current is gentle with small rapids and no dams, and we own both the put-in and the take-out — so the shuttle handles the rest. It's the easiest, closest crystal-clear river day trip within reach of Austin, San Antonio, New Braunfels, San Marcos, and Houston.
We're built for Texas families and friend groups, not the party-barge crowd. Pet-free, no booze cruises, no spring-break chaos — just a private stretch of river with riverside cabanas, covered picnic tables, tubes, kayaks, paddle boards, swimming, fishing, volleyball, and wide-open space to spread out. Stake out a base camp on the river in the morning, float and grill all day, and roll home by dinner — or stay the night and save 25% on day rentals.
