Grindle Point Light was established in 1851 on the offshore island of Islesboro. The light overlooks—and guides mariners into—Gilkey Harbor. The station features a square brick tower. You can take a ferry from the Maine State Ferry System to the island from the mainland town of Lincolnville. The station sits at the town ferry landing. In July and August, you can visit the Sailor's Museum inside the keeper's house.
