San Geronimo Ridge

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 change: 1,100 feet.

Please remember to bring a lunch and binoculars if you have them. We request that no pets (except service animals) attend this event.

Adverse weather or Air Quality Index (AQI) that exceeds 150 on may cancel events. Check the calendar or call (415) 473-6086 after 8 am on the morning of the event to hear a recorded message if canceled.
