Hamilton Pool Preserve

This preserve may be over 230 acres but the main attraction here is a swimming hole. Whether you want to take a dip or not, Hamilton Pool (Hamilton Pool Rd., FM 3238, Dripping Springs, 512/264-2740, 9 a.m.–5:30 p.m. daily, $8 per vehicle) is a sight worth seeing. It’s considered the most beautiful natural swimming hole in Texas because a majestic 45-foot waterfall spills into a deep, grotto-like pool that was formed when the dome of an underground river collapsed hundreds of years ago. In the hot summer months the preserve is usually filled to capacity. The parking lot can fit about 75 cars, and when all spaces are taken, cars are held up at the gate until a space opens. Drinking water or concessions are not available at the preserve, but there are toilets.

Thanks to a diligent parks and recreation department, the pool is carefully protected, and visitors are asked to be respectful of the environment. Swimming is allowed only when the water quality meets safe standards, so it’s best to call for swimming information before trekking out to the preserve. The preserve also offers limited day use for picnicking, hiking, swimming, and nature study. Pets are not allowed, even on leashes. Hamilton Pool Preserve is located about 30 miles west of Austin.
