Blue Hole Regional Park is a 126-acre Hill Country haven just outside Wimberley centered around its iconic spring‑fed swimming hole along shaded Cypress Creek The water remains a refreshingly cool ~75°F, and swimmers delight in rope swings, docks, and soft lawns nestled under towering cypress trees . Beyond swimming (which requires advance reservation during the May–Labor Day season), the park offers family‑friendly hiking and biking trails, playgrounds, sports fields, picnic areas, and event spaces—including a pavilion and amphitheater—for concerts, nature camps, and community events year‑round . Recognized twice as a Tripadvisor Travelers’ Choice attraction, Blue Hole blends natural beauty, conservation, and recreation—open daily from dawn to dusk with free access to all non‑swim areas .
