Acadia National Park preserves much of Mount Desert Island, and associated smaller islands, 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. The town of Tremont is home to Bass Harbor Head Light and is located on what locals refer to as the "quiet side" of the island. Cadillac Mountain, named after the French Explorer of the same name who went on to found Detroit, Michigan, is on the eastern side of the island. Its green, lichen-covered, pink granite summit is one of the first places in the United States to see the sunrise, making it a popular tourist attraction. 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.
