On sweltering summer days, the San Marcos River becomes a cooling respite for hundreds of tubers thanks to Don's Fish Camp. The shop rents tubes with coolers and sells supplies such as sunscreen and waterproof cameras for tubers to take onto the water. When not floating with a brew in hand, tubers can barbecue and picnic along the banks flush with trees and shrubbery.

The rec area accommodates those who aren’t ready to go home at the end of day by allowing guests to pitch a tent and camp under the stars to the sound of rushing water and largemouth bass that just won't shut up. To give these visitors a scenic place to tube and party, Don's team cleans up the riverbanks daily and requests guests bring no glass or styrofoam on the premises.
