» Redwood Hikes Map: Annotated trail map of Portola Redwoods State Park and Pescadero Creek County Park, Second edition, 2008. This is an excellent map sold by Dave Baselt ($6.95 in Dec 2011). This map is useful for exploring a bunch of parks: Portola Redwoods, Pescadero Creek, Sam Macdonald.
Route in brief:
The major trails along the route are Tarwater Loop Trail → Canyon Trail → Bear Ridge Trail → Brook Trail Loop → Pomponio Trail → Tarwater Loop Trail.
Since there are too many intersections along this route, a good trail map is necessary for this hike.
From I-280, take Page Mill Road 8.6 miles to Highway 35, cross the road and continue on Alpine Road for 3.8 miles. Turn left onto Camp Pomponio Road (there is a park sign on the left), follow it to parking lot. No fees was charged at this parking lot in Feb 2010.
