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

Once upon a time this was the only general store in this area, serving not only as a general-purpose retailer but also the post office, bank, and informal dentist's office. Nowadays it's a museum, staffed by docents ready to offer drop-in history lessons.

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.

There are a handful of trails here which treat you to views of the foothills across the reservoir. Upper Crystal Springs Reservoir provides water to the San Francisco Peninsula, and you can bike along its entire eastern shoreline.
