Bar Harbor. Bar Harbor is a resort town on Mount Desert Island in Hancock County, Maine, United States.
As of the 2020 census, its population is 5,089. During the summer and fall seasons, it is a popular tourist destination and, until a catastrophic fire in 1947, the town was a noted summer colony for the wealthy.
The town is home to the College of the Atlantic, Jackson Laboratory, Bar Harbor Bank & Trust and MDI Biological Laboratory. Bar Harbor is also home to the largest parts of Acadia National Park, including Cadillac Mountain, the highest point within 25 miles of the coastline of the eastern United States.
The town's main access road, from the north or south, is State Route 3, which is the coastal Eden Street taken from the Trenton Bridge. Upon entering the town limits from the north, Route 3 turns east onto Mount Desert Street, before turning south onto Main Street at Bar Harbor's Village Green.
It then circumnavigates the eastern portion of Mount Desert Island. Two other streets link Route 3 to Main Street: West Street and Cottage Street. Another principal road, Eagle Lake Road, leads west, from its intersection with Eden Street, Mount Desert Street and Kebo Street, into the national park.
