This year marks the 75th anniversary of the Golden Gate Bridge, so why not celebrate with a visit? Don't spend money on a tour; instead, download a free app (available for iPhone and Android) and learn behind-the-scenes trivia, get expert advice, and even listen to recordings of bridge workers' oral history. Walk or bike across the bridge and take in the fabulous views of San Francisco. Begin or end your visit with a stop in Golden Gate National Recreation Area, which can be accessed on either end of the bridge.
