Alcatraz, the historic island prison off San Francisco, opened up Monday for a limited number of indoor tours, which had been off-limits for more than a year due to the pandemic.
Face masks and social distancing are still required at the island, which once housed Al Capone and George "Machine Gun" Kelly. Ferries to Alcatraz are operating at 25% capacity, carrying about 150 passengers instead of the usual 600.
Access to the infamous cell house will also be limited only to visitors who sign up for the audio tour in advance.
