Our reservation system for the 2021 swim season at Blue Hole is now OPEN! Blue Hole Regional Park is a natural, spring-fed swimming hole lined with the iconic Cypress Trees located deep in the heart of the Texas Hill Country. The whole family will enjoy swimming in crystal clear water, sunbathing on the grassy swim lawn, and of course, swinging on our famous rope swings. The first day of our swim season is May 1st.
