Iona

Iona in Nova Scotia is an advanced dive site in the Bras d'Or Lakes on Cape Breton Island, offering a unique inland sea diving experience. The brackish waters of the Bras d'Or create unusual conditions where marine and freshwater species overlap. The site features steep rocky walls dropping into the depths of this landlocked sea, with cold, clear water providing good visibility. Lobsters, sea urchins, and cold-water anemones inhabit the rocky substrate alongside occasional freshwater species. The unique ecology of the Bras d'Or Lakes, combined with fascinating geological formations, makes Iona a truly distinctive diving destination.
