Havasu Falls is one of those Arizona destinations that are a must see. On Havasupai tribal lands deep within Havasu Creek Canyon, in the lower section of the Grand Canyon before it drops down to Lake Mead. It is about an 11 mile hike to the falls from the top of the plateau. Or, a short exciting 15 minute helicopter ride to Supai Village and a 3 mile journey from there. I have done both many times.
