Niagara II: cold-water Tobermory wreck with deep charter dives.
Niagara II (Wreck) is a purpose-sunk Lake Huron wreck off Tobermory, set up as a deep wreck dive with a clean upright profile, machinery, and penetrable structure. Expect cold, clear water, a deeper recreational profile, and a charter-based visit rather than a casual shore dive. The site suits certified wreck divers who are comfortable with cold water and managed penetration.
Site Conditions
Safety Notes
Use cold-water gear, stay within your wreck training, and treat penetration as an advanced wreck-diving task.
Access Restrictions
Boat charter only from Tobermory; public trips require certification, skill level, and cold-water experience.
Legal Notes
Deliberately sunk by the Tobermory Maritime Association and located outside the park boundaries, so follow charter and site rules.
Community notes to help plan your visit.
Scuba Diving
Advanced wreck charter with bow tie-ins, a deep upright hull, and interior features such as machinery and a wheelhouse.
Freediving
Not a freedive site; the depth, cold water, and wreck structure make it a scuba-only charter.
Snorkeling
Not a snorkel site; the wreck sits too deep and too cold for casual snorkel use.
