Located at the foot of bridge-free Grenadier Island in the Thousand Islands, this pet-friendly retreat offers sweeping views of Lake Ontario, Basin Harbor, and passing freighters. The home sits on 700 private preserve acres on a 1,200-acre island—with 15+ miles of maintained trails for hiking, biking, and ATV riding, plus abundant wildlife and wildflowers. The house itself occupies seven acres of lawn with a stone fire pit on the shore. You are renting far more than a house—this is a private nature adventure. Inside, the home blends old-stone charm with modern comfort: a master suite with balcony and marble bath, a queen bedroom, a twin room with lounge/pull-out sofa, and a 4-bed bunk room with loft. The guest stone cottage holds a full bed. Two additional marble bathrooms, four smart TVs, and a fully equipped kitchen (KitchenAid, waffle iron, warming drawer, ice-cream maker, new Thermador range) provide all conveniences. Enjoy hiking, swimming (private beach at the island’s head + flat-stone shoreline by the house), boating, birding, fishing, tubing, water skiing, and more. Included are a canoe, two kayaks, and a paddleboard. A restored 19th-century schoolhouse with original desks delights kids and adults alike. Fall is perfect for apple picking (many trees on property), hiking, bonfires at the new fire pit, or relaxing by the two fireplaces. If you venture off-island, Cape Vincent is a 15-minute boat ride, and Kingston, Ontario is \~40 minutes by boat (longer via ferry). Tennis, golf, shopping, museums, restaurants, and bars are all easily accessible once ashore. Boat access is required (5–10 minutes). Boat rental may be available with proven experience; caretaker can assist with transport and will greet you at the marina on arrival. Optional rentals: • 2 ATVs – $875/week each (+ deposit) • 4-seat Polaris + trailer – $975/week (+ deposit) • 22’ Grady–White w/ 250 HP – $1,500/week (+ deposit) Rates: • Base rate includes 10 guests (children/babies included).
