San Geronimo Ridge

This walk is for ages 18 and up. We’ll start the morning with a slow ascent from the valley floor to the San Geronimo Ridge. It’s a sustained climb but once we reach the top we’ll enjoy amazing views and the pygmy Sargent cypress forest that makes this preserve so unique. For lunch we’ll drop down to a shaded clearing among towering Redwoods and Douglas-firs. Distance: 5 miles; elevation gain: 1,200 feet. Remember to bring binoculars, if you have them.

High fire danger cancels: Call (415) 893-9527 after 7am on the morning of the event to hear a recorded message if cancelled. We request that no pets (except service animals) attend.

No registration is required.

Questions: Contact Shannon Burke at or (415) 893-9520.

Directions: From Hwy 101 in Larkspur, take the exit for Sir Francis Drake Blvd west 9.4 miles. Turn left onto Railroad Ave, sharp right onto San Geronimo Valley Dr, and take the second left onto Redwood Canyon Dr. The gate is immediately on the right.
