Kingston is a freshwater wreck-diving destination split between two sub-areas: Kingston Harbour and the Wolfe Island Graveyard. Shipwrecks dominate the site list, ranging from shallow beginner-friendly dives to deep advanced targets that reward those with experience. Artificial reefs add variety alongside the wrecks. Pike, Common Carp, and European Eel are regularly observed, giving dives a distinctly freshwater character. Summer brings the warmest water and the longest comfortable dive windows.

Some sites are well suited to beginners. Marmora Scuba Park offers a gentle shore entry and shallow depths, making it an accessible starting point. However, many of Kingston's most popular wreck sites are rated intermediate or advanced, particularly those in the Wolfe Island Graveyard and the deeper reaches of Kingston Harbour.
Kingston Harbour and the Wolfe Island Graveyard each hold a substantial number of sites. Both areas focus heavily on wrecks, but the Wolfe Island Graveyard leans towards intermediate and advanced dives at greater depths, while Kingston Harbour includes a broader spread of skill levels and some shallower artificial reef options.
The majority of Kingston's dive sites require boat access, including all of the top wreck sites such as the George T Davie, City of Sheboygan, and Katie Eccles. Shore entry is available at Marmora Scuba Park. Several local operators including Explorer Diving, Dive Force Scuba, and Pat's Dive Charters offer boat charters to the wreck sites.
