About this house rental

Escape the crowds at this well-maintained, air-conditioned 4-bedroom lakefront cottage with a separate A/C stone guest cottage (5th bedroom, no bath), a barn with a second floor unfinished game room (ping pong, foosball, weights), and a dock for up to four boats. 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). Take your own boat(boat ramp at marina) or boat rental may be available from owner, with proven experience, or arrangement can be made for transport by caretaker for a fee; 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). Additional guests $100/person up to 14 max.
• Dogs: $75/week each, max 2 (exceptions possible).
• Minimum stays: 7 nights July–August; 3 nights most of June & September.

New for 2025: Starlink high-speed internet, upgraded sound system, and WiFi extended to the guest cottage.

We stayed over the week of July 4th. 3 couples with adult kids. If you like the water, water sports, relaxing, nature and unbelievable scenery....this is an amazing place. The island is a short boat ride away and offers up a fantastic view in all directions. We took advantage of the kayaks, canoes, firepit by the lake, cornhole on the sprawling lawn, tubing, fishing, sunsets, ping pong, hikes, drinks on the deck, cruising on the lake and generally having a great time. John, the owner, is fantastic...great communication & information, responsive, etc...Although we spent most of our time outside, the house was spacious, the rooms comfortable and generally speaking, it had more amenities than we expected. The caretaker George is also super knowledgeable, thorough and accomodating. We'll be back!

This was our 4th year back to island and as always it was a great week. Lots to do exploring the trails on atv’s, fishing, swimming or going to the beach across the island all while enjoying the awesome scenery all around you. Then at night watching the beautiful sunsets every night with drinks in hand. It doesn’t get better than this.

A great place to spend a week and disconnect from the everyday life. Great property with lots or as little to do as you want. Very nice people to deal with for booking and our stay. It has become our home away from home.

Our family travels quite a bit, but this island now occupies a special place in our hearts! John (our host) and George (the property caretaker) both went above and beyond to make us feel welcome and make sure we had everything we needed. The house is both elegant and comfortable, and we felt at home immediately. We woke up to jaw-dropping views in the mornings, then went on day-long adventures all around the island. No one day was the same, and we kept finding new surprises and delights. We built a fire by the lake every evening to watch the stunning sunsets, and then we'd retire to the cozy library to collapse in the comfy chairs and enjoy our books or a movie. We left yesterday and I miss the island already!
