BMHS Fifield-Cahill Ridge Trail hike

~13 miles, 2500ft elevation gain. 

This is a one-way hike with car shuttle. This hike is limited to 25 people.

To attend this hike, you must register with Sharon at [masked] with required info below for SFPUC and for car shuttle. 

Located in the San Francisco P.U.C. Watershed property west of Crystal Springs Lake and the San Andreas Reservoir, the Fifield-Cahill Ridge Trail follows the property's main jeep road from Highway 92 to its boundary with Sweeney Ridge. This restricted segment of the Bay Area Ridge Trail features mixed woodlands and grassland, including both shade and open areas with views of the reservoir, ocean and northern peninsula. 

This trail is accessible only via registering with their docent led hikes. We'll meet at 8:30AM at South end of the trail. From there, we'll shuttle to San Bruno to start our 13-mile hike back to our cars, including all 10 miles of the Fifield-Cahill Ridge Trail. 

Bring plenty of water, lunch, hiking footwear and sun protection. Dress in layers since the weather may be unpredictable along the ridge. 

Please signup only if you can commit to making it. 

There will be a South Bay carpool setup at Lucky at Los Altos. To signup, you have to be willing to drive car shuttle unless you're in South Bay carpool or a self-carpool. 

In order to ensure having enough cars for the car shuttle, please signup with Sharon with the following info - 

(1) SFPUC requires name, e-mail, phone and city of residence for all participants.

(2) Are you going to be in South Bay carpool ?

(3) Are you going to be in a self-carpool? if yes, with whom? 

(4) If you drive to our hike meeting location will you be able to drive the car shuttle? 

You will be informed if you make into the participant list.

    Just wonder there is a permit to hike in water district land? SF water district has a reservation form online:

    Is this a fast pace hike? It is my first time to hike in a group. I don't know if I can keep up with the group though.
