Diving in Munising

Munising sits on the southern shore of Lake Superior within the Alger Underwater Preserve, and that protected setting shapes everything about diving here. Grand Island shelters many sites from open-lake conditions, making wrecks such as the Bermuda and the Smith Moore accessible to a wider range of divers than Lake Superior's reputation might suggest. Water is cold year-round: surface temperatures peak in late summer and drop near freezing for much of winter, while depth pushes temperatures down further still. Boat access is the standard approach, and operators run charters through late spring and into autumn. Visibility is among the best in the Midwest, which is why intact wreck hulls and submerged sandstone formations reward the effort of gearing up in a drysuit.
