Cranberry Island

Fallout 4 guide · uncovering the hidden bunker

Cranberry Island is an isolated location in the Far Harbor add-on containing an unmarked family tragedy and a hidden shelter. Players must locate three separate power generator stations scattered across the island to restore electricity to the bunker door. Once power is restored, you can enter Cranberry Island Docks to access the underground Cranberry Island Supply Shed and loot the stockpiled resources.
