If you go to Supai

The trailhead for the descent to Supai and the Havasu Falls is called Hualapai Hilltop, essentially a remote parking lot at the end of Arizona Indian Road 18.

To reach the trailhead from the west, go east some 70 miles from Kingman (90 minutes south of Las Vegas) on what is now Arizona Route 66 to Peach Springs. From the east, travel west on I-40 and take Exit 123 at Seligman and Route 66. Fueling vehicles in Kingman or Seligman is wise.

After a 65-mile drive from the west or about 35 from the east, turn onto Indian Road 18 and proceed 60 miles to the end of the road — Hualapai Hilltop.

• The closest lodging to the trailhead is in Peach Springs.

• Visitors are required to pay a $30 per person entrance fee in Havasu Canyon. (An American Indian with a tribal I.D. is exempt from this fee.)

• Reservations are required to visit and stay in the village of Supai and the canyon. For reservations at the Havasupai Lodge ($135 for four people), call 1-928-448-2111.

• The main campground area has toilets and drinking water. For reservations ($12 per person per day), call 1-928-448-2121. Reservations are accepted at the beginning of the year.

• Round-trip saddle/pack horses to the lodge cost $120, or $70 one-way. To the campground, it is $150, or $75 one-way. A Havasu Falls-only day tour by horse costs $60. Maximum person weight is 250 pounds. Helicopter rides in and out of the village are also available, if arranged in advance.
