How Deep d?id you say
Welcome to the 92-km Celtic Shores Coastal Trail, it stretches from Port Hastings to Inverness on the west coast of beautiful Cape Breton Island, Nova Scotia. The trail runs along side the Northberland Strait and the Strait of Canso. The Strait of Canso is more then 200 feet deep, and about 1 km at it narrowest point. Its funny it is always referenced that that way, it almost sounds like its 2x as deep as it is wide.
