SAN FRANCISCO (AP) — 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.

Safety modifications have been made throughout the island including social distancing markers, increased cleanings and hand sanitizing stations.

Food service will not be available on the ferries or on the island.

Alcatraz usually hosts up to 5,000 tourists a day. For now, that number will be reduced to about a thousand.
