Havasupai Falls

Hidden within a side canyon of the Grand Canyon on the Havasupai tribal lands, these electric blue-green waterfalls are unlike anything else on Earth. The travertine-rich water creates a series of cascades — Navajo, Havasu, Mooney, and Beaver — each more stunning than the last. Access requires a permit and a 10-mile hike or mule ride through red-walled canyons.
