About this site
The John B. King lies in the St. Lawrence River within the Thousand Islands region of Ontario, near Gananoque and close to the international boundary with New York State. This stretch of river is scattered with shipwrecks and rocky shoals, and the King rests on the bottom as a wreck dive rated advanced. The difficulty here reflects conditions typical of this part of the river, where current and depth demand a more experienced diver.
