Site description The Three Sisters Islands are located in the southern part of Lake of the Woods in northwestern Ontario. The town of Rainy River is about 35 km to the south. Two of the three rocky islands are vegetated with only sparse grasses, nettles and smartweed. The third island contains an area of shrubs and trees near its centre. There is little soil on the islands, and the climate is relatively dry, and prairie-like. The islands are situated well out in the lake, about 3 km from the nearest large land mass (Bigsby Island).
