Sonoma Ridge Trail

The Sonoma Ridge Trail is a portion of the Bay Area Ridge Trail and is about 9.5 miles out and back to the park boundary at the Ridge Loop through the woods above Jack London’s Beauty Ranch. Take the Sonoma┬áMountain┬áTrail to access the Sonoma Ridge Trail junction about 3 miles from the parking lot, mostly uphill. The featured hike starts at the Beauty Ranch parking lot, at about 700 feet and climbs to 2100 feet, then descends back to the trailhead. Elevation changes are mostly gentle, with numerous switchbacks. Continue past the park boundary on the East Slope Sonoma Mountain Ridge Trail to the Eliot loop for an additional 1.3 miles for a round trip of 12 miles.
