A quick tour of the Waterfall at Hamilton Pool Preserve. The waterfall is located 30 miles Southwest of Austin in Travis County near Dripping Springs and Bee Cave. The park is operated by Travis County Parks and is open to the public. The per-vehicle entrance fee is $15. Swimming is normally permitted, but sometimes water conditions forbid swimming. The trail down to the pool is about 1/4 mile, use caution as rocks and stairs can be wet and very slippery.
