Towering at nearly 196 feet, this waterfall is the largest and most difficult to get to of the three falls. A steep, dangerous descent makes clear access to the water nearly impossible. Extreme caution must always be used for hikers wishing to make the descent to further view the massive waterfall. Located approximately three miles from the reservation, the hike and subsequent climb to Mooney Falls is one that possesses slippery ledges requiring careful attention when making the trek to this wonder. The waterfall was named after D.W. James Mooney, a prospector who fell to his death in 1882 in an attempt to reach the bottom of the canyon. D.W. James Mooney was allegedly using a homemade ladder at the time he fell. Some accounts have said D.W. James Mooney was suspended by a rope for three days prior to falling. More accurate accounts indicate he slipped and fell when his rope snapped. Along the trail to Mooney falls, hikers will discover man-made tunnels blasted out of rock to assist those seeking to make the descent to the base of the falls. To avoid any unnecessary falls, a chain runs down the trail to give hikers something to hold on to. Because of the spray that comes from the waterfall, rocks nearby become wet and more slippery to those traveling downward to the base. A lesser known waterfall known as Beaver Falls sits an additional two miles downstream from Mooney and is around four miles from the Colorado River.
