Georgian Bay Outer Sites is a freshwater diving and snorkelling destination built around wall topography, artificial reef structure, and clear inland water. Cedar Hills typifies the area: shore entry, wall and artificial reef combined, and accessible to beginners. The fish life is characteristically freshwater, with Round Goby observed very commonly, Carp and Perch frequent across most sites, and Trout appearing occasionally. Conditions are warmest from midsummer into early autumn, when water temperature peaks and the season is most inviting.

The artificial reef elements in particular tend to concentrate fish life, which suits both divers and snorkellers exploring the shallower sections.
