Hamilton Pool, Texas
If you think swimming in a 5-star hotel’s swimming pool was your best experience, then you are absolutely wrong! Because swimming in the Hamilton Pool Reserve is definitely one of the best swimming experiences in America. The Hamilton Pool is a natural pool. It was created when the dome of an underground river had collapsed several years ago due to soil erosion. The site is popular among the tourists and residents of Austin. Hollywood movie Predators also featured this amazing natural pool.
