Most of the way you just follow a well-traveled wide sandy wash with no significant trouble spots. The road to the overlook is steep and rutted in places, but any high clearance 4×4 SUV should be able to make it. Flash floods possible in washes.
Time & Distance: The trail is 16.7 miles and takes 2 to 3 hours.
Directions to the Trail: From Tucson take Hwy 77 north about 14 miles past Oracle to the town of Mammoth. On the north side of Mammoth turn left on paved Camino Rio Road just before medical building. Turn left off the pavement immediately before going into the medical building parking lot.
