Located in Coconino County, the reservation sits at the southwest corner of the Grand Canyon National Park, considered one of America's most remote Indian reservations. The nearest community to the reservation is Peach Springs, Arizona, which lies approximately 64 miles to the southwest. The topography of the reservation is made up of plateau country, dissected with deep canyons. The plateau itself varies from rolling, gentle slopes, to escarpments of Kaibab Limestone. While similar to other locations within the system of canyons of which it is part, Cataract Canyon is unique due to the high concentrations of travertine in Havasu creek. The canyon itself is the largest individual side-canyon to the Grand Canyon. The presence of the travertine is what leads to the aquamarine color of the streams and ponds in the canyon. There is another small settlement at Indian Gardens.
