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.

You're not hallucinating: This monument was deliberately built in the style of ancient Greek and Roman architecture, to commemorate the Great Depression-era Hetchy Hetchy Project that brought water down from the mountains to the Bay Area. The frieze says, “I give waters in the wilderness and rivers in the desert, to give drink to my people.”

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.

While many of San Mateo's gravel routes feature significant climbs and can be quite challenging, some sections of trails, particularly around the Crystal Springs Regional Trail, offer more accessible and flatter options. The paved portions of the Crystal Springs trail are excellent for families, and some connecting dirt roads might be suitable for older children or those with more biking experience. Always check the specific route details for elevation and surface conditions to ensure it matches your family's ability.
Public transport access to gravel trails in San Mateo can vary. While some areas are reachable by local bus services or Caltrain, direct access to trailheads, especially in more remote mountain or forest preserves, might be limited. It's advisable to research specific bus routes or Caltrain stations that connect to areas like the Crystal Springs Regional Trail or other urban-adjacent parks. For routes deeper in the Santa Cruz Mountains, driving to a trailhead with parking is often more practical.

Yes, depending on the specific trail, you can find cafes and coffee shops in nearby towns or along more urban-adjacent routes. For instance, trails closer to Redwood City or Half Moon Bay will have more options for refreshments. The Crystal Springs Regional Trail, while scenic, is more secluded, so you might need to venture slightly off-trail into nearby communities for a coffee break. It's a good idea to plan your route and check for amenities in advance.
Generally, permits are not required for gravel cycling on most public trails in San Mateo County's open space preserves or regional parks. However, it's always a good practice to check the specific regulations of the park or preserve you plan to visit, as rules can change or vary for certain areas or activities. Some private lands or specific conservation areas might have different access policies.
