For recreational wreck divers, historic shipwrecks loom beneath the surface and create unforgettable experiences in coastal locations and freshwater lakes.
From the Great Lakes to Guam and from the East to West coast, explore the USA’s maritime history at these marine sanctuary and national park locations. Remember to take only photos and leave the wreck sites completely intact. These vessels provide a window into the past and are best left undisturbed for everyone to experience. Check with local officials to determine if diving permits are required.
Channel Islands National Marine Sanctuary, California
About 2,672 square kilometers of ocean and near-shore habitat off the southernCalifornia coast make up the Channel Islands National Marine Sanctuary. The maritime heritage here is vast with an inventory of more than 140 shipwrecks documented between 1853 and 1980; yet only 20 have been located. Weather conditions can change quickly in this area, a main factor for many of the shipwrecks among the islands.

Located in Lake Superior, Isle Royale is a wilderness area 72.4 kilometers long and 9.6 kilometers wide. The water around the island is clear and the below-15.2-meter water temperature is the same year-round, two degrees above freezing.
Thunder Bay National Marine Sanctuary
On November 23, 1907, after hours of fighting a gale in northwestern Lake Huron, the crew of the wooden steamerMonohansett took a chance to regroup, only to be faced with a fire that quickly sank the ship. All 12 crew members made it to safety. Today, theMonohansett's steel propeller and lower hull are visible in 5.4 meters of crystal-clear water.

Gateway National Recreation Area and Fire Island National Seashore
An area known as “Wreck Alley” just minutes from the heart ofNew York City is a wreck divers’ paradise. Gateway National Recreation Area and Fire Island National Seashore are surprising entry points to an area where hundreds of shipwrecks dot the landscape below the surface. And outside the park boundaries are well known wrecks like theUSS San Diego, Oregon,Black Warrior, Mohawk and theAndrea Doria.
Cape Hatteras National Seashore, North Carolina
Known as the “Graveyard of the Atlantic,” Cape Hatteras National Seashore and theOuter Banks are meccas for wreck divers. Topography, weather and currents made for treacherous sailing conditions and caused many shipwrecks for merchant ships. During World War II, the Germans launched an attack sinking more than 80 ships. There are also wreck sites among the sand dunes, and depending on shifting sand, one can observe the skeletons of ships as time and erosion converge to dismantle these vessels.
Olympic Coast National Marine Sanctuary, Washington
As a protected wilderness area, the 117-kilometer coastline of Olympic National Park is a unique treasure and gateway to the Olympic Coast National Marine Sanctuary. While diving from the beach is not an option, boat diving off shore and within the sanctuary provides a window to more than 150 historical shipwrecks on the ocean floor. Weather was the biggest factor in the demise of most ships along this coastal stretch as more traffic flowed in and out of the Puget Sound in the 1900s.
