Libby Island Light Station was established at the often-foggy entrance to Machias Bay in 1822. The current tower was constructed of granite in 1848. The light is not open to the public and the keeper's house and other outbuildings no longer exist. Charter boat rides and cruises offer views of the tower.
Beginning May 1, travelers from all states will be able to travel to Maine without providing a negative COVID-19 test result or quarantining, unless otherwise determined by the Maine CDC. If a state experiences a spike in COVID-19 cases, the Maine CDC will apply testing and quarantine protocols to all travelers from that state.
