50 Travel Destinations Every American Simply Must Visit In Their Lifetime

21. Hamilton Pool – Dripping Springs, Texas

If you’re ever in the Austin area, you may want to consider visiting the Hamilton Pool. It’s a natural formation that has attracted many tourists to swim in its cold waters during the hot summer months. The pool was naturally formed when the dome of an underground river collapsed after centuries of erosion, exposing the large area to the rest of the world. So bring your swimsuit and your sunblock for a few hours of swimming and relaxing at the water’s edge.
