Warren Richardson Trail is a gravel and dirt fireroad path in Annadel State Park leading from the main entrance and parking lots on the Park's eastern side to the height of the main ridge and then slightly down to beautiful Lake Ilsanjo near the middle of the park.
There it connects with the Canyon Trail, the fireroad leading down on the western side and then north to the Santa Rosa Reservoir in Spring Lake Park.
