This gem is well worth the trek in. Lower Navajo is one of 4 (ish) falls that you can enjoy when you make it past the village. This particular waterfall is perfect for a jumping jump off into the pristine waters. Once inside the canyon, this is also your drinking water for the duration of your visit. So bring some kind of a filter. There is a plethora of information available on the web as to how and when to visit Havasupai. It is truly magestic, and unlike anyplace else on earth.
