The Forest Park portion of Granite Trail begins at the "P-4" parking area on Reservoir Road. As you head down from the road, a junction is soon reached with the Halls of Manzanita trail and the hiker-only Cantrall Canyon trail. Turning left down Granite, expect a speedy downhill with some natural features to exploit before you come to the quarry parking area ("P-2") on Reservoir Road.
