Fathom Five National Marine Park
Where It Is: Lake Huron’s icy waters preserve sunken ships for decades with little disturbance. Fathom Five Marine Park, a land and water reserve on Lake Huron’s Georgian Bay at the end of the Bruce Peninsula, is a four-hour drive north of Toronto.
What to Look for: With 22 significant shipwrecks dating back to the 19th century, Fathom Five presents a microcosm of maritime history. The wrecks include shallow-water hulks that even snorkelers can enjoy, but also wood-hulled schooners more than a dozen fathoms deep. Among the latter is the Arabia, a schooner that sank in 1884; according to Dan Orr, the CEO of Divers Alert Network, the ship’s bowsprit “points a lonely finger towards the surface nearly 100 feet above.”
