Great spot to start a hike in the Marin Headlands. 
This is the entrance to the Morning Sun trail which takes you to the Alta trail. From there you can access many miles of hiking trails including Rodeo Beach, Hawk Hill, Tennessee Valley, Hawk Camp and many more.

Golden Gate 70/80 drops of here and you can also walk from the Sausalito Ferry Terminal.
