The Fundy Shore covers the area of Southwestern New Brunswick. Here the tide is not as extreme (compared to the Southeastern shore, near Fundy National Park), and the coast has many rocky points and depths ranging from approximately 10-50'. It is deep enough to support a variety of marine life, although conditions can be poor with storm surge and poor visibility.
A popular site for a "quick easy dive" has been New River Beach, as it is close to Saint John and even a reasonable drive from Fredericton. It is not deep, and an easy entry so used frequently by divers practicing skills. This is also a provincial park with overnight camping.
Beaver Harbour has long been a favourite of divers across central and southern NB. It often has better visibility than the other Fundy Shore sites. It can only be accessed by crossing private land now though, so access may become blocked in future years. For now, the owners have tolerated divers using the private road to access the beaches for diving.
Wallace Cove (Black's Harbour) is near the Grand Manan ferry terminal so can even be a planned dive while waiting for the ferry! Often the visibility is poor here though, unfortunate as the site seems to attract a number of marine critters and it can be quite an interesting dive.
