2. The Best Secret Swimming Holes

What's better on a hot summer day than jumping into a cool swimming hole with a big splash? The Blue Hole in New Mexico is a crystal clear-blue artesian well that is a pleasant 64 degrees F. all the time. It's a favorite of scuba divers, with visibility up to 80 feet. Another Blue Hole, this time in Texas, is part of Blue Hole Regional Park, and offers a cool, spring fed blue pool that's inviting for swimming on a hot day or just lazing around on an inner tube. For a little more excitement try one of the 3 rope swings. Yet another blue hole (there seems to be a pattern forming here) called Peekamoose Blue Hole, located in New York, offers a deep, cold, deep, aqua-colored pool with a rope swing at the deepest end.
