The inbound hike distance will be approximately 3.59 mi. or 4.59 mi. Depending on where you park.
If you use two vehicles park one at the west end, mm 9, go uphill find the Cache and then go back down the other trail and pick up the other vehicle at the trail head that is East of where you parked the 1st vehicle.
Bring water its dry up there, and no place to use a filter.
