Explore the shipwrecks of the Thunder Bay National Marine Sanctuary. The crystal clear waters and our large ‘glass bottom’ viewing wells allow you to dive the wrecks – without getting wet. During our 2 hour cruise you will experience the magnificently preserved shipwrecks and the scenic shorelines of Thunder Bay. Learn the exciting tales of many famous ships and the history, legends and lore of Lake Huron.
