Deer Isle is a town in Hancock County, settled in 1762 and incorporated on February 2, 1789 from Deer Isle Plantation. Much later it set off land to form the towns of Isle au Haut (1874) and Stonington (1897).
The town occupies the northern two-thirds of the island of Deer Isle and all of Little Deer Isle.
At Northwest Harbor, Deer Isle is almost split in two. The remaining narrow land area, at the village, is known as the Haulover.
The Deer Isle-Sedgwick Bridge, which can be see from Sedgwick, is a spectacular suspension structure arching over Eggemoggin Reach Sedgwick on the mainland. It was constructed in 1938 and opened to traffic in 1939. Its main span is 1080 feet long and the total length is 2,248 feet.
Barred Island nature preserve, managed by The Nature Conservancy, is a .2 acre island with spruce-fir and shrub-cover and extensive granite shore ledges. Accessible by landing on inter-tidal sandbar or across private property with permission of Goose Cove Lodge owners, the island has no trails though one may walk along the shore. Little Eaton Island is also a sanctuary managed by the Conservancy.
