Site details

A cold-water wreck and wall diving hub on the islands around Byrknes in Gulen, on the western fringe of Sognefjord about two hours north of Bergen and home to the well-known Gulen Dive Resort. The area concentrates dozens of wrecks and dramatic fjord walls draped in anemones, soft corals and sponges, popular with technical and underwater-photography divers. Sites range from shallow scenic walls to deep wrecks, and conditions are sheltered inside the fjord system though water is cold year-round. It is one of Norway's premier wreck destinations, served by a resort with on-site fills and gas.
