Mooney Falls is the fourth main waterfall in the canyon. It is named after D. W. "James" Mooney, a miner, who in 1882 – according to his companions – decided to mine the area near Havasu Falls for minerals. The group then decided to try Mooney Falls. One of his companions was injured, so James Mooney decided to try to climb up the falls with his companion tied to his back, and subsequently fell to his death. The Falls are located 2.25 miles (3.6 km) from Supai, just past the campgrounds. The trail leads to the top of the falls, where there is a lookout/photograph area that overlooks the 210-foot (64 m) canyon wall that the waterfall cascades over. In order to gain access to the bottom of the falls and its pool, a very rugged and dangerous descent is required. Extreme care and discretion for the following portion is required; it is highly exposed and should not be attempted when the weather and/or conditions are not suitable.
