Best approach is to climb up hile at "Trailhead." Continue up trail about 100 feet to rustic bridge on right. Cross bridge and head downhill, more or less parallel to the way you came up. Cache is hidden at edge of drainage, in crevice.
You can approach using the most direct route but it's more precarious that way and not recommended!
Parking is rough as you would just be double parking unless you park and hike from elsewhere. High curb over here, or be quick while pulled to the side!
GLHF!
