36 Bostwick Island, The Thousand Islands: An 11-Acre Estate. Discover a rare 11-acre parcel on Bostwick Island, minutes from the Gananoque Marina in the heart of the Thousand Islands. This historic 6-bedroom, 4-bath summer home (circa 1909) has been lovingly maintained by a full-time caretaker and offers unmatched privacy, charm, and natural beauty. Stretching the full width of the island from north to south, the property showcases a scenic pond with a fountain, rugged gardens, and winding trails throughout. Relax on the sand beach, enjoy deep water swimming at the dock, or enjoy time in the hot tub and sauna. The marine facility is terrific; a wet slip boat house with shop/repair space, a second covered slip and extensive other docking. This Summer Home features a grand covered verandah, stone fireplace built from island-quarried stone, main-floor principal suite, a private office/den and an updated kitchen. Upstairs, you'll find 4 charming bedrooms and 2 bathrooms. Outdoor living shines with a hot tub for sunset views, sauna, and spectacular island vistas to the north west from the covered, huge verandah and over the 40 Acres to the south. First time on the market in many years, this is truly a jewel of the Thousand Islands, offering history, privacy, and timeless waterfront living.
