Havasupai Trail is the main trail to Supai and to Havasu Falls. The trailhead is located at Hualapai Hilltop (which is located at the end of BIA Road 18), where there is a large parking lot, a heli-pad and permanent toilets that include amenities such as toilet paper and hand sanitizer. The trail can be traveled by foot, by horseback, or on a mule service the Havasupai offer. The mule service can also be purchased for luggage/packs only, which allows an easier hike and the ability to bring down more luxuries. The trail starts out at the hilltop, where it switch-backs down the side of the canyon for about ¾ of a mile. This is by far the most difficult part of the trail, and is much more difficult on the way back up. The trail is approximately 8 miles (13 km) long to Supai, with an extra 2 miles (3.2 km) added on in order to reach the campgrounds, and descends about 2,000 feet (610 m).
