San Andrea's Lake View

Highlight • Viewpoint

Beautiful stretch of biking/walking path, relatively flat with a few short minor hills. The view of the lake is gorgeous!

Tip by

13.9 km

San Andreas Lake is a hidden gem tucked into the hills of San Mateo County, just south of San Francisco. Originally a natural sag pond formed by the San Andreas Fault, it was transformed into a reservoir in the late 1800s and now serves as a vital water source for the region. The lake is off-limits for swimming or boating, but you can enjoy its peaceful beauty from the San Andreas Trail or the popular Sawyer Camp Trail, which runs along its eastern edge. It's a serene spot where you can walk or bike with sweeping views of the water and surrounding hills, all while standing right on one of the world’s most famous fault lines. Despite its proximity to urban life, San Andreas Lake offers a quiet, scenic escape steeped in natural and historical significance.

Lower Crystal Springs Reservoir

Highlight • Lake

The 15-mile Crystal Springs Regional Trail is one of the best mostly paved bike trails with few cars in the Bay Area. It spans from San Bruno to Woodside and is routed along three gorgeous lakes and connector links amid riparian woodlands. On Sundays, you can combine the San Andreas and Sawyer Camp segments to south of Highway 92 to Cañada Road, which is closed to cars for Bicycle Sundays (See komoot.com/tour/11413421)
Speed limit: 15 mph, difficult for high-end road bikes to stay below, so bring a bell: some hikers stand and talk in the center of the trail ;-)
San Andreas segment: From Skyline Boulevard south of San Bruno Avenue the trail drops to the head of San Andreas Lake, with pretty views across to the west of the wilderness slope of Montara Mountain. It rides along the lake 2 miles to an access point near Larkspur and 0.6 miles to another (at Hillcrest) where it connects to the Sawyer Camp segment.
Sawyer Camp segment: This is a gorgeous, easy bike ride, where you drop 400 feet over the span of 6 miles to Crystal Springs Dam. The route descends into riparian woodlands for 2.5 miles to Jepson Laurel picnic grounds, then runs along Crystal Springs Reservoir for 5.2 miles. You can continue another 1.7 miles to Cañada Road for Bicycle Sunday (no cars).
Cañada Road/Crystal Springs segment: South along Upper Crystal Springs Reservoir for 2.1 miles to the Pulgas Water Temple. It continues another 2.1 miles past Filoli Botanical Center and Phleger Estate to Edgewood Road

San Andreas Lake

Highlight • Lake

This used to be a small, natural pond, but was expanded with the help of an earthwork dam that miraculously survived a famous earthquake in 1906 that more or less took place right underneath the dam. Because this is a reservoir you can't swim in it, but there's a great multi-use trail that you can follow as far as the Crystal Springs Dam.

Centennial Way Trail

Highlight (Segment) • Cycleway

The Centennial Trail is a section of paved path that helps make up the South San Francisco biking trail network. This is primarily a commuter trail, but it also works great as a spot for everyone in the family to ride, or even a way to pass through town during your ride without having to stick to the busy streets.

Sister Cities Park Trail

Highlight (Segment) • Trail

The Sister Cities Park Trail follows Colma Creek all the way to Orange Memorial Park. You can tie into the more popular Centennial Trail here.
