Mooney Falls at the end of the Havasupai Campground and approximately one mile from Havasu Falls is the tallest of Havasupai's waterfalls and plunges some 200 feet in an impressive singular column amongst the ominous-looking travertine stalactites. This waterfall towers higher than Niagara Falls. The waterfall's name originated from the prospector D.W. James Mooney who fell to his death over the side of the falls in 1882. Mooney Falls is a little harder to access and view given its somewhat enclosed position, but the hike leading up to the top of Mooney Falls is pretty straightforward. You'll face a steep cliffside descent and a lot of drop-off exposure, plus a pair of tunnels to reach its base. It appears to be a pretty scary experience that looks worse than it is, but as long as you take your time, this beautiful place hidden in the Grand Canyon is worth the frightening climb down the ladders and chains along the canyon wall.
