Don't go chasing waterfalls

The stunning limestone travertine steps of Beaver Falls are the last in a series of five waterfalls along Havasu Creek, near the bottom of the Grand Canyon. The water gets its turquoise color from calcium carbonate, which reflects the beautiful hue and creates an ever-changing tableau; the minerals are deposited, moved, and redeposited to create new formations.

Getting to Beaver Falls is only for the adventurous—and lucky. First, you need a permit for Havasupai campground, which typically sell out in a day. From there, it's a 4-mile strenuous hike on rugged terrain with frequent water crossings, narrow ledges, and chains and ladders to assist when the trail gets especially precarious.

Your persistence is rewarded with pools for swimming, a natural waterslide, and stunning red rock canyon views. It's no wonder this region is sacred to the Havasupai, whose name means 'people of the blue-green water.'
