Grand Manan Island (also simply Grand Manan) is a Canadian island, and the largest in the Bay of Fundy. It is also the primary island in the Grand Manan Archipelago, sitting at the boundary between the Bay of Fundy and the Gulf of Maine on the Atlantic coast. Grand Manan is jurisdictionally part of Charlotte County in the province of New Brunswick.
The island rests in the midwestern end of the Bay of Fundy, a body of water between the provinces of New Brunswick and Nova Scotia, and home to some of the strongest tides in the World. Located 32 kilometres south of Blacks Harbour, the point on mainland closest to the island is in Washington County, Maine, near the town of Lubec - the easternmost point of the continental United States, where the distance to the island measures 15 km (9.3 mi) across the Grand Manan Channel.
Grand Manan is 34 km (21 mi) long and has a maximum width of 18 km (11 mi) with an area of 137 Square Kilometer (53 Square Mile). The vast majority of Grand Manan residents live on the eastern side of the island. Due to limited access, three-hundred-foot cliffs and high winds, the western side of the island is not residentially developed, although it does feature wind-power ventures and camps at Dark Harbour, a small dulsing community and get-away destination for islanders.
Grand Manan has a network of trails for all-terrain vehicles, hiking, mountain biking, nature walks, and presents a challenging landscape for jogging. There are a number of fresh-water ponds, lakes and beaches that are prime locations for sun-bathing, beach combing, and picnics. Other interesting finds on Grand Manan are magnetic sand, and The Hole-In-The Wall located in Whale Cove in the village of North Head.
