The Hamilton Pool Preserve is a historic swimming hole with 50 foot limestone waterfalls. During droughts the waterfalls slow to a trickle. Swim at your own risk (when swimming is allowed). There are no lifeguards on duty. Swimming is sometimes prohibited due to high bacteria levels. For updated swimming conditions please call (512) 264-2740 before you come.
It is just under a mile upstream from its confluence with the Pedernales River. The pool trail is 1/4 mile in length and includes a series of rock steps descending into the canyon. The trail is rugged and steep. Sturdy footgear is recommended. Visitors with physical disabilities can arrange assistance into the canyon by requesting a ride by preserve staff. The ride takes a visitor into the canyon, but not all the way to the pool, since no vehicle can make it to the pool.
