StandoutRich in charismatic marine life

The Prim Reefs, off Nova Scotia, give you a real taste of North Atlantic diving. You’re not getting tropical corals here, but a hardy ecosystem supporting species like Atlantic cod and saithe. Keep an eye out for American lobsters tucked into crevices and the surprisingly colourful green sea urchins clinging to the rock. We often spot common jellyfish pulsing by and, if you’re lucky, a curious butterfish might swim past. It’s a solid dive for those who appreciate cooler waters and a different kind of marine beauty.
