Hamilton Pool Preserve in Texas: How to Visit This Awesome Swimming Hole

The Hamilton Pool Preserve is part of the Balcones Canyonlands Preserve and has been a designated nature preserve since 1990. The 232-acre nature preserve focuses on habitat protection, restoration, and habitat for wildlife.

In order to keep the area pristine, access to the pool is by reservation only, daily from March to October with weekend reservations required November until December. The pool is a quarter mile from the parking lot, but note that the path is rocky and steep in areas.

The natural pool, surrounded by limestone slabs, is fed by Hamilton creek. Its 50-foot waterfall never completely stops flowing, but in the dry season it slows to a trickle — interestingly, the pool’s water level stays pretty constant.

The water quality is constantly monitored, and sometimes the pool may not be open for swimming. The preserve allows swimming only on days when the bacteria levels and rainfall are in a safe range. Call the public information line to find out the status: 512-264-2740
