Hamilton Pool Preserve
A semicircular limestone sinkhole pool formed when an underground river collapsed. A 50-foot waterfall pours over the rock overhang. It is one of Austin's most photogenic natural sites.
Hamilton Pool is located about 30 miles west of the city. It is a natural pool formed thousands of years ago when the roof of an underground river collapsed. Emerald water, stalactite-lined overhangs, and a cascading waterfall make it a spectacular sight. Timed-entry tickets must be reserved in advance on the Travis County website (about 12 dollars per vehicle plus 8 dollars per person). From the parking lot, it is a downhill walk of about 1 kilometer to the pool. Swimming depends on water quality and the risk of falling rocks that day, and it is often prohibited, so visitors may only be able to look.
