Hamilton Pool Springs, TX

## Overview Hamilton Pool Springs is a stunning natural spring located in the Texas Hill Country, approximately 30 miles west of Austin near the community of Hamilton Pool, Travis County. The spring feeds the renowned Hamilton Pool Preserve, a spectacular collapsed grotto where Hamilton Creek spills over a dramatic 50-foot limestone overhang into a jade-green natural swimming pool below. The site was formed thousands of years ago when the dome of an underground river collapsed, revealing a breathtaking half-open grotto adorned with stalactites, lush hanging ferns, and moss-covered canyon walls. The area surrounding the spring sits within the Balcones Canyonlands and is part of a 232-acre nature preserve managed by Travis County Parks. Hamilton Pool has been a beloved swimming and recreation destination for generations — it was originally discovered by settlers in the 1880s and was used as a swimming hole by the Reimers family, who owned the surrounding ranch land for decades. The preserve was designated a protected area in the 1990s to help conserve its unique ecosystem, which includes the golden-cheeked warbler, a federally endangered songbird. The spring-fed pool maintains relatively cool water temperatures year-round, making it an especially popular destination during the hot Texas summers. Water quality is periodically tested by Travis County, and swimming is occasionally restricted when bacteria levels exceed safe thresholds — visitors should check the Travis County Parks website or call ahead before planning a swim. The GPS coordinates for the spring are approximately 30.3424, -98.1270. ## Directions 1. From Austin, head west on TX-71 (Ben White Boulevard). 2. Continue on TX-71 for approximately 24 miles past Oak Hill. 3. Turn left (south) onto Hamilton Pool Road (FM 3238). 4. Follow Hamilton Pool Road for about 13 miles as it winds through the scenic Hill Country. 5. The entrance to Hamilton Pool Preserve will be on your right. 6. Note: A day-use reservation is typically required, especially during peak season (spring and summer). Reservations can be made through the Travis County Parks website. There is a per-vehicle entrance fee. ## What to Expect Upon arriving at the preserve, visitors will park in the designated lot and follow a well-maintained but moderately steep trail approximately a quarter mile down into the canyon to reach the pool. The trail descends roughly 200 feet in elevation over limestone steps and a natural path — sturdy footwear is recommended. At the bottom, the grotto opens up dramatically. The waterfall cascades over the limestone lip into the emerald pool below, surrounded by towering canyon walls draped in maidenhair ferns and other lush vegetation. The pool area includes a small natural beach of gravel and rock. During periods of heavy rain, the waterfall flow increases significantly, creating an even more impressive spectacle. Swimming is allowed when water quality tests pass — check current conditions before your visit. The preserve has a limited daily capacity to protect the fragile environment, so arriving early or booking reservations in advance is strongly recommended. Facilities are minimal: there are restrooms near the parking area but no concessions or changing rooms. Bring water, sunscreen, and any supplies you'll need. The preserve is open daily but hours vary by season. Dogs and glass containers are not permitted. The trail and pool area are not wheelchair accessible due to the steep, uneven terrain.
