Parking is on Wiley Canyon Road (the dead end section orphaned when the street was realigned -- accessible from Wabuska Street).
Enter the streambed just past the curve under a large tree. At some point you will need to exit the streambed and make your way up the hill the best and safest way that you can. There are a number of possible trails.
Long pants and hiking boots are advisable. The trails are steep and can be slippery. Not recommended after dark or during inclement weather. Watch out for rattlesnakes and other critters. Rabbits, birds, native plants and views abound.
There are other trailheads, but note that many of the streets East of here are private streets.
Cache is within a few feet of the quints. Easiest access in the last 50 feet is from the Southwest to avoid creating geotrails.
