Scapa Flow is a natural harbour in Orkney whose floor holds one of the most significant collections of shipwrecks accessible to recreational divers anywhere in the world. The German High Seas Fleet was scuttled here in nineteen nineteen, leaving battleships, light cruisers, and destroyers spread across the seabed alongside Second World War blockships. Sites in our database range from very shallow shore dives to advanced boat dives beyond forty metres, covering all skill levels. Water temperatures are cold year-round, and most diving is conducted via boat charter from Stromness. Visibility typically runs from five to twenty metres. The wrecks carry dense growth of plumose anemones, and the surrounding area also holds reef, seagrass, and a variety of temperate species including ballan wrasse, pollack, saithe, and grey seal.
