Get a feel for the history of Alcatraz Island for free in San Francisco. Celebrate the 55th anniversary of the federal prison closure with Parc 55 San Francisco and Alcatraz: Life on the Rock exhibit. Starting late February, there will be a speaker series with former guards, a prisoner and residents of the island. The Hilton San Francisco Union Square will also participate by holding a couple of choice exhibit items in their lobby. The exhibits and events stretch until late June. Check out the exclusive Alcatraz Escape Weekender Package, including accommodations and a self-guided tour to both exhibits, offered by both Parc 55 and Hilton Union Square (starts at $259/night).
