Site description Point Lepreau and Maces Bay are located along the northern coast of the Bay of Fundy, about 30 km southwest of Saint John. The point forms the eastern border of Maces Bay, Welch Cove, and Little Lepreau Basin, which make up the marine areas of the site. These marine areas contain intertidal reef ledges bordered by mud flats, and a few shallow inlets. Several islands are also present including New River Island, and The Brothers (Salkeld Islands). Intertidal reefs and waters extend about 10 km south from the point into the Bay of Fundy. The shoreline is low and rises gradually, with low cliffs and reefs exposed at low tide. The tidal range is 6 to 8 m (not as dramatic as the tides of the upper bay).
