The hike that locals refer to as “Crown Road” is really an assortment of fire roads and regular trails on the slopes of Mount Tamalpais above Kentfield accessed from a trail head at the end of Crown Road.
From Hwy 101 in Larkspur, take the exit for Sir Francis Drake Blvd west 2.1 miles. Turn left onto College Ave, right onto Woodland Rd, left onto Evergreen Dr. Continue uphill to the intersection with Ridgecrest; 50-feet uphill from this junction, left onto Crown Road, and follow to end (dead end). There is room to turn around at the dead end and parking is along the street (parallel parking). If it is a weekend and you have to park a bit away, just consider that part of your hike!
