Nothing quite prepares you for that first quiet moment, walking down to the dock as the early morning sun begins to rise, its warmth gently breaking through the cool air. The day awakens slowly here. Loons call to one another across the water, and the soft rhythm of waves brushing against granite shoreline and towering trees sets a pace all its own. Life in the Thousand Islands isn't for everyone. It's for those who truly understand the value of natural beauty-the ever-changing sky, the brilliance of a clear summer day, and sunsets that feel almost unreal. It's for those who cherish evening boat rides, refreshing morning swims, laughter shared around a picnic table, and the simple joy of a homemade meal outdoors. Fishing, water sports, and moments that become lifelong memories-this is where they happen. For those who appreciate it, this place doesn't just impress-it stays with you. Dumfounder Island is one of the area's true hidden gems. Located less than ten minutes from the marina on just over 9 acres, you can leave the mainland behind and arrive at your private dock in minutes. The existing cottages are captivating in their simplicity, modest, authentic, and perfectly positioned to take in everything the island offers. There is space here. Space to explore, to expand, or simply to preserve what has been loved for generations. Whether you envision building more or keeping it just as it is, this island offers something increasingly rare: a sense of permanence, of legacy. This is more than a property-it's a place your family returns to, year after year. Come experience a sunrise. Stay for a sunset. ***There are four outbuildings and one pump house. The main cottage has a Living Room with a fireplace, a kitchen,2 piece washroom, Bedroom. The Second has a Bedroom, a 3-piece bath, and a sitting area; the third has an open Bedroom with a woodstove and a 3-piece bath. The fourth has a toilet and sink and is currently used for storage.
