All Cars, all paved. On Montezuma Valley Road, 1 mile up the grade, park in the parking area.
At the parking, head west, at a well marked trail head.
The canyon can be seen strait ahead, crossing the California Riding and Hiking trail that bends to the left.
At [3] crossing a trail from the Visitor Center (from the right). Move along and often across the wash coming out of the canyon.
At times the trail is difficult to find, but take time to look for the easiest way.
The end is obvious at the Maidenhair falls. Water may be absent at the end of the dry season (October).
The end is obvious at the end of the year, but not always in spring, when there are 2 falls close to the end (seasonal) and some hikers stop at the first fall and never make it to the maidenhair that is only about 100 Yards further.
Fee: Hellhole Canyon requires a parking pass, pay at the parking.
