Among your first stops should be Marin Headlands Visitor Center. Here, you'll be able to find your bearings and get lots of useful information before you start exploring.
This tourist information center is on the to-do lists of many visitors to Sausalito. But Marin Headlands Visitor Center isn't the only highlight in the area. Golden Gate Bridge, Alcatraz Island, and Lombard Street are some other worthwhile attractions close by.
