For the past 160 years, the beacon from Blue Hill Bay Lighthouse on Green Island has lit the way for ships coming in from the Atlantic Ocean.
It lies in an isolated spot, with views towards the mountains of Acadia National Park, and is just over an hour’s drive from Bangor’s airport. The island has a big sandy beach, and at low tide it has acres of sandbars.
The house has four bedrooms, a wood stove and a full kitchen. Agent: Vladi Private Islands (0049 4033 8989; vladiprivate-islands.de)
