One of my favorite things to do in Marin is take the 10 minute ferry ride from Tiburon to Angel Island. Spend the day hiking, biking or relaxing at the Angel Island Cantina. Angel Island also offers Tram tours and Segway tours around the 6-mile perimeter of the island. Both are great ways to get views of the Golden Gate Bridge, San Francisco and San Rafael. Have a picnic with boxed lunches ready when you arrive on the island provided by the Angel Island Cafe. Angel Island has something to offer for everyone!
