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.

The Sausalito houseboat community is full of architectural gems and repurposed old working boats, and each is wonderfully unique. Bikes are not allowed on the dock, so you must park your bike to get a closer look; however, remember to be respectful when visiting, as these are residential homes, and you are close to someone's living space.
