Hamilton Pool Nature Preserve

Hamilton Pool Preserve is a natural pool located about 37 km west of Austin, Texas, United States. The attraction of the park is a 15m waterfall over the edge of a cave that collapsed forming a beautiful pool of blue and green water. The trail from the parking lot to the pool is a bit rocky and allows visitors to have a panoramic view of the area around the pool.
The 1990 movie The Hot Spot, with Jennifer Connelly and Don Johnson, filmed scenes at Hamilton Pool.
