the typical boat houses north of San Francisco

This isn't the sort of road you'd take a vehicle on, nowadays - but it's great for nontechnical mountain biking, and this high point gives you nice views over the surrounding hills.

Sausalitoβs floating homes form a lively and unique community of over 400 houseboats anchored in Richardson Bay, just north of San Francisco. Originally emerging in the late 19th century as simple fishing huts and weekend getaways, these structures transformed over time into a refuge for artists, writers, and free spirits. After World War II, many abandoned materials from shipyards were repurposed to create imaginative residences, reflecting a deeply creative and unconventional way of life. Crafted from reclaimed wood, former ferries, and even repurposed streetcars, these homes became icons of counterculture living. During the 1970s, locals fiercely defended their alternative lifestyle in the "Houseboat Wars," a pivotal movement that safeguarded their place in Sausalitoβs history. Today, these floating dwellings blend architectural eccentricity with bohemian charm, providing a relaxed, water-based way of life that thrives on creativity and strong community bonds.

If you're riding into Sausalito from San Francisco then you'll be coming in via Alexander Avenue. You'll be treated to great views across the water, and the classic Bay Area homes built along the cliffside.

One of the most popular viewpoints over San Francisco, Twin Peaks lives up to the hype. As long as you make your journey up before the fog rolls in you'll be treated to sweeping views across the city.

You get a great view of this little reservoir as you ride by, especially when heading north. The reservoir has been around for well over 150 years. There are bike lanes on both sides of Laguna Honda Boulevard.
