About this site
Lake Simcoe sits in south-central Ontario, north of Lake Ontario and roughly an hour's drive from Toronto, feeding into the Trent-Severn Waterway via Lake Couchiching to the north. It is one of the larger inland lakes in the province, known primarily for ice fishing and recreational boating rather than as a dedicated dive destination. Diving here is rated beginner.
