These two towns are located on the southern end of Mount Desert Island, just across from each other at the entrance of Somes Sound, near the gorgeous, 35,000- acre Acadia National Park. They front deepwater harbors and are full of summer fun. In Northeast Harbor, there are the lovely Asticou Gardens, a strawberry festival, a seafood festival, a farmer’s market, live music on Main Street every Thursday evening, ice cream socials … More than 400 members belong to the Northeast Harbor Fleet, and nearly every day of their calendar in July and August offers a club event or regatta — except Tuesdays, which is apparently the sailing Sabbath. Southwest Harbor is home to a gaggle of great boatbuilders, including the Hinckley Co., Wilbur Yachts, Ellis Boat Co. and Ralph W. Stanley. Islesford Dock Restaurant on Little Cranberry Island is a favorite local outing for residents of both towns.
