Tunnel Trail
Detailed Description
This view from the Tunnel Trail is looking down (west) toward the Chaparral parking area on the west side of the park. Chaparral and scrub oak forests blanket the lower hillsides in the region. The hills east and north of the park are underlain by Cretaceous-age granitic rocks that weather differently from the Tertiary volcanic rocks in the park.
