About Big Tub shipwrecks
The waters around Tobermory hold more than 20 shipwrecks, protected by Fathom Five National Marine Park. The lake’s cold, fresh water preserves wood well, and the clarity allows hulls to be seen from above.
In Big Tub Harbour, next to the village, are two of the best known wrecks. The schooner Sweepstakes ran aground in 1885 and lies in shallow water a few meters below the surface, with much of the hull intact. The steamship City of Grand Rapids caught fire in 1907 and sank nearby.
Glass-bottom boats pass over both wrecks en route to Flowerpot Island. They can also be seen by kayak or snorkeling, and the area is a cold-water diving destination. At the harbor mouth stands the wooden Big Tub Lighthouse, built in 1885.
