Hualapai Hilltop is reached via Indian Route 18, which you follow about 65 miles north from historic Route 66 (34 miles west of Seligman and 50 miles east of Kingman). The total driving distance from the South Rim of the Grand Canyon is about 200 miles and takes about four hours.
The Havasupai restrict the number of visitors to the canyon; you must call ahead and make reservations. The 8-mile Hualapai Trail begins at Hualapai Hilltop. You can park your car here (the parking lot is patrolled), but there is no gas, lodging, or water available. From an elevation of 5,200 feet, the trail travels down a moderate grade to Supai village at 3,200 feet. Bring plenty of water and avoid hiking during the middle of the day, when canyon temperatures can reach into the 100s. You'll need to spend the night if you're hiking, as no day hiking is permitted; there's a campground 2 miles farther in ($17 per person) or the Havasupai Lodge in the village.
Another option is a helicopter ride into the canyon with Air West Helicopters. Flights leave from Hualapai Hilltop four days a week during summer and two days a week during winter, and cost $85 per person each way. Reservations aren’t accepted and visitors are transported on a first-come, first-served basis. Tribal members are boarded prior to tourists, but all are assured of a ride down, as long as you arrive at the Hilltop by 1 pm. All visitors, whether camping or staying at the lodge, must pay a $40 entrance fee.
