Pleasanton Ridge Letterboxes
Boxes 1 through 6 have now been placed
This is a string of boxes along the length of Pleasanton ridge. The park is several miles long and there is (at time of writing) only one point of access- at the southern end of the park. Times and mileages given are cumulative. For example Box 1 will take about 1.5 to 2 hours if you turn back after finding that box. If you find boxes 1-4 you will cover 9.6 miles and take about 5-6 hours round trip.
The trail head is at the Oak Tree staging area off of Foothill road south of Castlewwod Drive.
The first part of this hike is steep.
Box 1 Olive Grove
2.5 miles (approx 1.5-2 hours) round trip for this box
From parking area take Oak Tree trail to the Woodland trail. Follow the Woodland trail to top of ridge and through the gate until it intersects the ridgeline trail. Follow ridgeline trail looping around the hill to the olive grove trail. Then follow olive grove trail until you come to the first olive grove on right. From the tree in the NW corner count 4 trees south along trail and 3 trees east, in from trail. Look in the hollow tree.
UPDATE: The hole in the olive tree has gotten deeper in the six years since the box was placed. The box is wrapped in camouflage tape that has turned dirt brown over the years. I have attached some bailing wire to the box and left the free end sticking outside the side of the hole (there is a sort of slot on the western side of the hole). Find the wire (rusty) and pull, up and out of the hole, and the box should follow.
