Take State Route 374 and turn on to Big Pine Road. From there, follow the signs to Conkle's Hollow where you will travel a dead-end drive back to the parking area and trail head.
When you get on the trail, head toward the Upper Rim Trail designated by the many steps. Since this is a preserve, you must stay on the marked trails! Also a word of caution-the upper section of Conkle's Hollow is over 200 feet in the air in some places and the trail is along the edge. Don't take kids here and certainly, use your common sense.
