Swan Dive and Cygnest, it's aptly named guest house, are located at a coveted location on 1.9 acres with waterfront on the Great Harbor of Southwest Harbor, across from the popular Causeway Club. There are two residences, the larger, original seasonal residence with full kitchen, classic living room with fireplace, dining room, four bedrooms and four baths, as well as a newer, stylish one-bedroom, year-round residence with full kitchen and full bath. Both are extremely attractive in their own way: the older, classic, gracious wood paneled style, and the more recent design build, with bright open spaces, fine pickled wood paneling and large windows. Both have quality appliances and appointments, and have been beautifully kept and maintained in great condition over the many years. Wonderful, engaging views from the property are of five nearby islands and the entrance to Somes Sound. Sailing and cruising yachts as well as lobster boats traverse the waters and provide endless activity to view from the spacious lawns, decks, and granite terraces at the two residences. A deep water seasonal dock and moorings are a huge asset. The entrance to 25 North Causeway Lane is particularly attractive, with a lovely reflecting pond with granite bridge and waterfall; huge old growth conifers and maples frame the circular gravel drive and lawn. Perennial plantings and specimen trees throughout the property provide additional color and privacy around the open lawn and garden areas. There is also a four car garage with storage area above, privately set apart from the residence, an excellent complement for this unusual offering.
