CharacterReef dive

StandoutRich in charismatic marine life

Lewis Reef, off Nova Scotia, offers a decent dive experience for those exploring Canada’s Atlantic waters. We’ve found the rocky ledges here are home to a respectable number of species, with American lobsters tucked into crevices and Atlantic cod often cruising by. Keep an eye out for yellowtail flounder camouflaged on the seabed, and depending on the season, you might spot salmon making an appearance. It’s a solid pick for divers keen to see what the colder North American waters have to offer, without the expectation of tropical colours.

Safety Notes

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