This is a very scenic trail that is best enjoyed in the spring. The trail heads out from the back of the Pacheco Camp, which is a nice place for a lunch break if you're using this trail as part of a longer ride.
It is not heavily used so may be overgrown with grass. You'll be crossing Pacheco Creek multiple times so prepare to get your feet wet. There are a number of trails to the right and left that are steep climbs up to the surrounding ridges along the way. It is pretty well signed and ends with another pretty steep climb up to Willow Ridge Road.
