Located approximately 30 miles southwest of Austin, Texas, the Hamilton Pool Preserve is a natural historic swimming hole. Located 3/4 mile upstream from its confluence with the Pedernales River, Hamilton Creek spills out over limestone outcroppings to create a 50 foot waterfall as it plunges into the head of a steep box canyon. The waterfall never completely dries up, but in dry times it does slow to a trickle. However, the pool’s water level stays pretty constant, even during periods of drought.
Formed thousands of years ago by the collapse of a large grotto (cave) into Hamilton Creek, the pool is surrounded by huge slabs of limestone that rest by the water’s edge; large stalactites grow from the ceiling high above.
