Fathom Five National Marine Park of Canada
The deep and sparkling waters at the mouth of Georgian Bay are home to Fathom Five - Canada's first National Marine Conservation Area. The park preserves a rich cultural legacy that includes 22 shipwrecks and several historic lightstations. Fathom Five's freshwater ecosystem contains some of the most pristine waters of the Great Lakes. The rugged islands of the park are a reminder of the impressive lakebed topography found beneath the waves.
