The Havasupai Indian Reservation encompasses about 300 square miles of rolling plateau and an intricate maze of cliffs. The Hualapai Trail is the only route into Havasu Canyon maintained for public use.

The canyon environment is remote, harsh, and unforgiving. Hiking here can be extremely dangerous even for experienced hikers in top physical condition. Temperatures can be extreme, water is scarce, the terrain is often steep. Use the utmost caution in planning and spending time in the canyon. You are responsible for your own safety and well being.

Those coming from the west on Interstate 40 exit onto Route 66 at Kingman, Arizona; those coming from the east turn off at Seligman. Supai is reached by a good paved road, Highway 18, that travels sixty miles from Route 66 to the trailhead at Hualapai Hilltop. There are no facilities along this stretch, so stock up on gas, food, and water.

Nearing the Hilltop the road winds down a tributary canyon until the ground seems suddenly to drop away. There is a bleak, paved parking area that has been leveled on a broad bench on the side of Hualapai Canyon.

No roads connect the village of Supai with the outside world. The only access is by foot along the Hualapai Trail, on horseback, or by helicopter. Get directions from MapQuest.
