Tips from the Community
Climbing up Mount Tamalpais, you'll find many great spots for admiring the scenery, but this one particularly struck me because, almost immersed in nature, you can see the city skyline in the distance. I found it so moving that I stopped my bike and stood there contemplating the landscape for a few minutes. The climb is a bit steep, but it's definitely worth it!

The Old Tiburon Rail Trail is a scenic 2.6-mile path along the San Francisco Bay, with breathtaking water views and Mt. Tamalpais. Starting at Blackie's Pasture, it winds past coastal mudflats full of wildlife before transitioning into an on-street bike lane leading to downtown Tiburon. It's a fantastic, smooth ride with historical markers, parks, and a ferry terminal at the trail's end, making it an ideal place to enjoy nature and local history for a day away from the big city.
