Located on the southwestern side of Mount Desert Island, Southwest Harbor is known for its working waterfront, maritime heritage, and access to Acadia National Park's landscapes. The harbor supports boating, sailing, fishing, and other coastal activities, while the village center features locally owned shops, restaurants, galleries, and everyday services. Nearby trails, mountains, forests, and rocky shoreline provide opportunities for year-round outdoor recreation.

Southwest Harbor's housing includes village residences, classic coastal cottages, waterfront properties, and larger private parcels throughout the surrounding area. Local roads connect the community with neighboring Mount Desert Island villages, Acadia National Park destinations, and the regional amenities of Bar Harbor. Southwest Harbor continues to attract buyers seeking coastal access, outdoor recreation, and the character of an established Maine harbor community.
