Bigwin Island is a 520 acre private island located on beautiful Lake of Bays in the heart of Muskoka. It is home to Bigwin Island Golf Club – a world-renowned private golf course nestled within the island, residential cottage properties, and 80 acres of common lands that create generous buffers between the Golf Course and the residences. BIWA, the Bigwin Island Waterfront Association, is an incorporated not-for-profit association of approximately 102 property owners who call the island their ‘home away from home’.
