Crystal Springs Reservoir Trail

Trail Map

Description Suggest an Edit

Note: Crystal Springs Dam crossing is closed for reconstruction. Access is from the north via the Black Mountain/Hayne Exit off I-280, west to "T" intersection, turn left (south) on the frontage road, approximately 1 mile to park.

The Crystal Springs Reservoir Trails are made up of two trails: the San Andreas Trail and the Sawyer Camp Recreation Trail. Both are wide, flat, paved trails winding around the eastern shore of the Crystal Springs Reservoir.

San Andreas trail extends from San Bruno Avenue on the north to the south end of San Andreas Lake, where it connects to the Sawyer Camp Trail. The Crystal Springs Reservoir Trail has easy access to Skyline Boulevard. The southerly 0.7 mile has a gravel surface and impassable by bicycles, which have to detour to the frontage road east of I-280 to get to Sawyer Camp Trail. The trail passes close to San Andreas reservoir in its northerly section and provides beautiful views. Trail managers hope to one day connect the trail to the Sweeney Ridge Trail and the San Francisco Bay Discovery Site.

The Sawyer Camp Trail is 6 miles long and runs along the Shoreline of Lower Crystal Springs Reservoir to San Andreas Lake. It's the most popular trail in the San Mateo County Park system, and for good reason. It's an easily-reached, incredibly scenic trail that takes you closer to forbidden Crystal Springs Reservoir and San Andreas Lake than any other trail.

The trail follows the path of the old wagon route that was the main travel lane between Half Moon Bay and San Francisco. You can get to the southern entrance by taking the Bunker Hill exit from I-280, heading west, then turning right on Skyline Boulevard. Drive over Crystal Springs Dam and look for a parking spot.

Parking and Trail Access

To access the San Andreas Trail segment, park along SR 35 (spaces available) near the John Muir Elementary School. Parking for the Sawyer Camp segment is near Crystal Springs dam and near where Lifemark Road, SR 35 and Ralston Avenue meet.

Really enjoyed this bike ride. If you're looking for something extremely flat and scenic and paved this is the trail for you. Make sure to bring plenty of water and some snacks with you. What's nice is there are bathrooms on the trail¿ read more
