Scapa Flow features the remains of the German High Seas Fleet, including four light cruisers and three battleships. These wrecks, which range from 24 to 45 metres in depth, offer historical features such as guns, steering wheels, boilers, anchor capstans, and bows. The site is strictly for advanced divers due to depths, moderate currents, and variable visibility between 3 and 20 metres. Access is by boat only, and a drysuit is highly recommended given the water temperatures of 8 to 13C. Species recorded around this area include orange-clubbed nudibranchs, sea stars, common sea stars, crabs, rock crabs, snails, and sea squirts.

F2 is a reef site located within the Scapa Flow Wrecks area. Divers should be prepared for water temperatures ranging from 8 to 13 degrees Celsius, necessitating the use of a drysuit or thick wetsuit. Conditions at this site are variable, with currents that may require advanced drift diving techniques. All entries and exits must be conducted from a boat. Divers are advised to monitor depth closely to manage decompression and nitrogen narcosis risks. Given the shifting nature of local visibility and tidal movement, checking tide tables and recent reports is essential before planning a dive. Divers should arrive self-sufficient with all necessary equipment.

The SMS Karlsruhe is a German Imperial Navy light cruiser scuttled in 1919. Lying on her side, the wreck sits at depths between 12 and 27 metres, with an average depth of 25 metres. Divers access the site via boat, with dives typically lasting 40 minutes. Visibility ranges from 10 to 20 metres, allowing for views of the hull and superstructure. Due to moderate currents and cold water temperatures between 8 and 13 degrees Celsius, a drysuit is essential. The site presents hazards including entanglement risks, potential down currents, and nitrogen narcosis at depth. Divers must plan carefully around narrow tidal windows to ensure slack water.

The F2 Barge is a wreck and artificial reef located in Scapa Flow, United Kingdom. Resting at depths between 8 and 18 metres, this site is suitable for beginner divers. The wreck provides structural shelter, with mild currents allowing for a relaxed exploration of the hull. Visibility is variable, ranging from 5 to 20 metres. Due to cold water temperatures between 8 and 13 degrees Celsius, a drysuit is essential. Divers should remain cautious of sharp edges and potential entanglement points throughout the structure. Access is by boat only, and guided tours are available locally to assist with site navigation.

The SMS Markgraf is a scuttled German First World War battleship lying on its side in Scapa Flow. This wreck site features depths ranging from 19 to 45 metres, with an average depth of 35 metres. Divers can explore the hull, gun turrets, and superstructure. Access is by boat only, and the site is suitable for advanced divers due to the overhead environment and potential for entanglement. Visibility typically ranges from 10 to 30 metres. Water temperatures remain cold throughout the year, between 8 and 13 degrees Celsius, necessitating appropriate thermal protection. Moderate currents are present, and planning dives around slack water is recommended.

SMS König is a scuttled German battleship located in Scapa Flow. The wreck sits upright on the seabed, with the main deck at approximately 16 metres and the hull reaching 42 metres. This site is suited for advanced divers capable of navigating large steel structures. Access is by boat only, and dives typically last 30 minutes. Conditions include moderate currents and visibility ranging from 5 to 20 metres. Water temperatures are cold, between 8 and 13 degrees Celsius, making drysuit diving essential. Divers should be aware of hazards including boat traffic and entanglement risks. Slack water is the recommended window for diving, and coordination with a charter skipper is necessary.

The SMS Dresden is a scuttled German Imperial Navy cruiser located in Scapa Flow. The wreck lies at depths ranging from 25 to 38 metres, with an average depth of 32 metres. Divers can explore the exterior of the vessel, which features encrusting marine growth. Access is by boat only, situated 1000 metres from the shore. Conditions include moderate currents and visibility typically between 12 and 20 metres. Water temperatures range from 8 to 13 degrees Celsius, making a drysuit and thermal underlayer essential. Due to the depth and potential for entanglement, this site is suitable for intermediate divers. Air fills are available locally.

SMS Kronprinz Wilhelm is a German High Seas Fleet battleship resting upright in Scapa Flow. The wreck spans depths from 12 to 40 metres, with an average depth of 30 metres. Divers can explore the main structure, including massive gun turrets and intact hull plating. The site is accessible only by boat, located 1200 metres from shore. Conditions feature mild currents and visibility between 10 and 20 metres. Due to the cold water temperatures of 8 to 13 degrees Celsius and potential overhead environments, a drysuit and wreck certification are recommended. Divers should be aware of entanglement hazards and the deep nature of the site.
