The San Marcos River brings a steady stream of people to San Marcos to tube down its 72-degree waters year-round. Let your troubles float away past Rio Vista Park, where the Lions Club tube rental shuttle picks people up or a quick visit to the Korner Stop can set you afloat. This part of the river has deep pools that flow into three chutes known as Rio Vista Falls. About 14 minutes east of San Marcos in Martindale, Texas State Tubes, run by Bobcat Alum, and Don's Fish Camp offer shuttles to and from the river and all the tubes and gear you'll need for your day in the sun.
