Diving & Snorkeling.

The Sweepstakes — a 36.3 m two-masted schooner built in Burlington in 1867 and sunk in Big Tub Harbour in September 1885 — rests in 6.1 m of water about 46 m from the harbour head, with the hull mostly intact. It is the entry-level snorkel and dive site that anchors Fathom Five National Marine Park.

Twelve-plus deeper named wrecks lie offshore across the archipelago, plus three non-wreck sites at Dunks Point, Big Tub Lighthouse Point, and The Anchor.

Diving & Snorkeling in Tobermory
01 — What to know

The brief.

Fathom Five is Canada's first national marine park (1987), 112 km², preserving 24 documented shipwrecks. All scuba divers must register and purchase a dive pass at the Tobermory visitor centre or a downtown dive shop before diving; snorkellers do not need a dive pass.

Water is cold and exceptionally clear — wood wrecks are preserved largely intact, but cold-water exposure planning is required even in mid-summer. The Niagara II (28 m), Arabia (33.5 m), and Forest City (18–46 m off Bear's Rump Island) sit in the advanced range; Sweepstakes and the Big Tub Harbour wrecks are the entry-level lane.

June through September is the working window.
