Explore above and beneath the waves of Lake Huron in Thunder Bay National Marine Sanctuary. Whether cruising as a passenger aboard a glass bottom boat, paddling your own kayak, or snorkeling from shore, a calm day on Lake Huron can provide amazing views from above. The range of depth of the shipwrecks appeals to a variety of diver skill levels and also provides opportunities for non-divers. The sanctuary maintains seasonal moorings at many shipwreck sites. Available from May to September, the moorings make for safer diving and also protect shipwrecks from anchor damage.
