People have traveled on the Great Lakes for thousands of years. During the “Shipwreck Century” (1825-1925), technology transformed maritime travel and small wooden sailing vessels evolved into giant steel steamers. Millions of trips were made across the lakes; most were successful, but not all. Fire, ice, collisions, and storms claimed both ships and lives. Today, nearly 200 shipwrecks lie in Thunder Bay National Marine Sanctuary. Preserved in clear, fresh Lake Huron water, these shipwrecks offer world-class diving, snorkeling, and paddling opportunities. Visitors can experience the sanctuary by climbing the steps of a lighthouse, joining a snorkel expedition, taking a glass-bottom boat or kayak tour, or plunging below the waves to explore a majestic schooner, while leaving the shipwrecks as they were found for the next generation to enjoy.
