San Marcos River at Rio Vista Park

River · Texas

About this swimming hole

Three spring-fed chutes tumble through this free city park, creating natural slides and plunge pools in the middle of San Marcos. The San Marcos River holds at 72 degrees year-round, fed by the Edwards Aquifer a few miles upstream. It is the classic broke-college-kid swimming hole: free, fun, and five minutes from campus.
