Perimeter Road is the main road that rings the small island of Angel Island. The road is not flat, and can be trafficked only by bicycles, but it makes for an amazing little tour of the island, with spectacular views along the way of San Francisco, the Golden Gate Bridge, and the infamous island of Alcatraz. Bikers on the Perimeter Road will encounter all of the major historical sites on the island, from the Immigration Station to the abandoned military facilities, as they cruise through the island. Near the Immigration Station, bicyclists have the option of turning inward and biking the Fire Road Loop, which rises to a higher altitude and also encircles the small island.
