Tips from the Community

David B. Davis
August 31, 2025, Burlingame Caltrain Station

Caltrain is bike friendly. Read on their website how to do it, then hopon, got to San Jose or San Francisco and ride around there. It makes a great day.

A fun, pretty place to stop while riding CaΓ±ada road. I has water and an air pump and bathrooms. Take a photo with friends.

The station is small, and has a little park by the platform. The Burlingame Hillsborough History Museum is contained within the station, which is historic in its own right. Be sure to check out the exhibits for photographs and stories of the town's past.

Looking northeast down the hill, on a clear day you can see all the way out across San Francisco Bay to Mount Diablo.

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, β€œI give waters in the wilderness and rivers in the desert, to give drink to my people.”

Devils slide itself is nice and just to the south is the beautiful Gray Whales Cove beach. There is plenty of parking at both places. Two notes for cyclist: 1. cycling along Hwy 1, coming from Pacifica, requires climbing on a relatively narrow but highly frequented road. It is not a long climb until the turnoff to Devils slide, but it might be stressful for cyclists who are not used to riding in heavy traffic. Hwy 1 south of Devils slide has enough space for everyone. 2. If you cycle on Hwy1, then check the wind forecast beforehand. Dominant wind direction is NW, which means cycling southbound maximizes tailwind and minimizes breathing in all the air pollution from stinky cars.

The Crystal Springs Regional Trail is a top spot for cyclists, featuring mostly paved paths with minimal car traffic. The trail runs through scenic areas like Lower Crystal Springs Reservoir, offering beautiful lake views. On Sundays, you can ride the car-free CaΓ±ada Road segment for a more relaxed experience. Be mindful of the 15 mph speed limit, especially around hikers. The Sawyer Camp segment provides a gentle descent and stunning views, perfect for an easy ride through woodlands and along the reservoir.
