Route: Big Rock Ridge (CA)

Big Rock Ridge is one of the most recognizable features in Marin County, and has sustained views on all sides for several miles. Starting from the Big Rock trailhead on Lucas Valley Road, climb immediately up to the top of the ridge, then follow fire roads generally down the ridge until reaching the Ponti ridge mountain bike trail. Take a left and follow all the way down to the Terra Linda-Ignacio bike path for the last half mile to the parking lot.
