CharacterReef dive

StandoutRich in charismatic marine life

Nova Scotia diving often gets overlooked, but places like Hell Reef remind us why we love exploring the colder waters. Dropping down, you’re greeted by a surprisingly robust coral system, especially for this latitude. We’ve spotted plenty of winter skates cruising the bottom and even a few razorbacks hunkered down in the crevices. Keep an eye out for blue sharks slicing through the deeper water, particularly in late summer. It's a site that rewards patience and a good dry suit, perfect for divers keen on seeing what the North Atlantic truly has to offer beyond just wrecks.

Safety Notes

Cold water this month (avg 15°C). Drysuit or thick wetsuit (7mm+) recommended.
