Dorset Quarry in Vermont—once a stone mine that provided marble for the likes of the New York Public Library—is now a swimming hole open to the public.

No hiking is required! The quarry is right off the highway.

Located on the Havasupai Tribe Reservation, the swimming hole at Havasu Falls is a doozy to get to but well worth it (just look at the pics!). You'll need a permit, and the journey involves a 10-mile trek (or a helicopter or mule ride).

Fun fact: Havasupai means "people of the blue-green water."

Take a detour off the Blue Ridge Parkway for this 60-foot water slide courtesy of Mother Nature.
