The Iona Bridge at Grand Narrows is one of the most popular dive sites in Cape Breton and a must to see when you are a diver.
Even if you are a novice diver and you do not feel comfortable to see the wreck in 20m, you can spend a full day diving around the piles in 5m, being protected by the bridge against the current.
This is a spot full of colours and marine life, and you will see many different animals.
