Drawbridge is a ghost town nestled on an island in the salt marshes of south San Francisco Bay. In its heyday around the 1920s, as many as 600 people visited Drawbridge on weekends to enjoy its rustic atmosphere, and to go hunting, fishing, boating and swimming. Some people remember it as a quiet, peaceful town full of nature lovers, while others claim it was a rip-roaring town full of two-fisted rowdies. Over time, residents and visitors abandoned the town. In 1979 Drawbridge saw its last resident move out. Since then, it has become a ghost town and is slowly sinking into the marshlands.
Warning: No Trespassing Allowed! Drawbridge is now part of the Don Edwards San Francisco Bay National Wildlife Refuge and is no longer open to the public. It is illegal and unsafe to visit the town. Trespassers on federally-managed land may be penalized with large fines. Drawbridge can be briefly viewed from the Altamont Commuter Express, Capitol Corridor, and Coast Starlight trains. The U. S. Fish and Wildlife Service conducts a Drawbridge Van Excursion led by long-time volunteer Ceal Craig on a periodic basis. The tour does not visit the town itself; it only goes to the closest spot from which one can legally view Drawbridge.
