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 worldโs most famous fault lines. Despite its proximity to urban life, San Andreas Lake offers a quiet, scenic escape steeped in natural and historical significance.

Woodside Store was built back in the 1850s by two pioneers who came to California for the gold rush. At the time it was the only stagecoach stop between San Francisco and Santa Clara, and it carried all the essential items that travelers riding between cities might need. The store has been restored, inside and out, to look exactly as it did centuries ago. You can call the museum ahead of your trip to book tours.

Ravenswood is a multi-use trail that encircles a wetland on the edge of the San Francisco Bay. You are likely to encounter a high number of local and migratory bird species while exploring the area, and though noise can be an issue near the highway it gets much quieter the further out you go.

The San Francisco Bay Trail consists of over 350 miles of interconnected trails around the eponymous bay. This section, between the urban sprawl and evaporation bonds for salt mining, won't win any awards for its scenic views. However, it is a nice separate trail that allows you to ride away from road traffic.
