As a cultural region, Downeast Maine encompasses the rural communities of Hancock and Washington counties. Principal Downeast towns include Calais, Eastport, and Machias. Bar Harbor, Blue Hill, and Ellsworth can also be considered Downeast communities. It also includes Acadia National Park and environs. There are three National Wildlife Refuges in the region: Cross Island National Wildlife Refuge, Moosehorn National Wildlife Refuge, and Maine Coastal Islands National Wildlife Refuge (formerly Petit Manan National Wildlife Refuge).

Acadia National Park preserves much of Mount Desert Island, and associated smaller islands, off the Atlantic coast of Maine. The area includes mountains, an ocean shoreline, woodlands, and lakes. In addition to Mount Desert Island, the park comprises much of the Isle au Haut, a small island to the southwest of Mount Desert Island and parts of Baker Island, also nearby. A portion of Schoodic Peninsula on the mainland is also part of the park.

The town of Bar Harbor is located on the northeast corner of Mount Desert Island. Southwest Harbor, on the western side of the fjord Somes Sound, is well known for boat-building and fishing, and has the largest year-round population on Mount Desert Island. Northeast Harbor is known for its beautiful private "cottages" yet retains a small town atmosphere. Cadillac Mountain, named after the same French Explorer who went on to found Detroit, Michigan, is on the eastern side of the island, and has always been a famous tourist destination because its pink granite summit is one of the first places in the United States to see the sunrise. Miles of scenic carriage roads were originally built by Rockefeller, Jr., with great sensitivity to the trees and contours of the land. The mountains of Acadia National Park offer hikers and bicycle riders views of the ocean, island lakes, and pine forests.
