Description

This trail is mostly a loop (the Hanna Lane Trail completes the loop). It goes through a good portion of the northern part of Shell Ridge Open Space and is easy to pick up anywhere on the loop. There are several steep hills that are rutted and loose from time to time.

This description starts at the end of Hanna Lane in Walnut Creek.
