Wasaga Beach is the world's longest freshwater beach (14km or 8.5 miles). It is approximately 2 hours north of downtown Toronto and abuts, to the west, the resort town of Collingwood. Its position on the waters of Nottawasaga Bay means its summer temperatures are moderated somewhat by the water, so summer days are much more comfortable than Toronto's scorching days, but the same winds off the water trigger very heavy and intense snow squalls in the winter. As such, snowmobiling, skiing, and other winter sports are extremely popular along the beach.
