    StandoutExceptional marine biodiversity

    Diving Caye à la Tête de Cheval in Québec feels more like an expedition than a typical reef dive. Forget tropical colours here; this is a place of rugged, cold-water beauty. We've seen wolf-fish lurking in rocky crevices and the curious stare of a moustache sculpin tucked amongst the green sea urchins. Visibility can be a bit variable, but when it’s good, the underwater topography is dramatic, and the sheer number of Atlantic cod and halibut is impressive. It’s a site for divers who appreciate the unique challenges and rewards of northern diving, especially those keen on spotting some less common North Atlantic species.
