After about a mile, it climbs out of the forest and intersects with a short spur down to Alpine Road.
The trail continues left across a grassy hillside with nice views looking west toward the ocean. Stay left at the Bo Gimbal Trail
. Soon you'll reach Charquin Trail
, where a left will take you down to the Mindego Lake Trail and back to the trailhead, and right will take you up to other trails and eventually to Skyline Boulevard.
