Dive Conditions: Churchill Barriers

About Churchill Barriers

The Churchill Barriers are four causeways built across Scapa Flow's eastern entrances during World War II, and the blockships deliberately sunk to seal those same channels before construction are now beginner-friendly wrecks at 2–8m depth. The salvage work left tangled steel, telegraph wires and intact hull sections draped in kelp and jewel anemones — an accessible introduction to wreck diving requiring only a shore entry at low tide. The shallow depth means extended bottom time, and the WWII history is vivid at this scale.
