Good for you, rv2go ! Also known as the "Chocolate Falls".
Hard to find kinda - on the Navajo Rez east of Flagstaff. Road to it is "OK" - it has a Indian Hwy designation. The road is impassable crossing the river when the water is high for the falls - the falls are dry most of the time.
We had been snowed in at the Grand Canyon Trailer Village (but made for great photography!) and then went to Sedona and to the Grand Falls from there.
We were very fortunate as to the timing.
For more pix go to and click on Grand Falls under AZ - you can also see my Grand Canyon winter shots right above it.
