Why dive here
With 66+ marine species recorded in the area - including jellyfish lake - ERNA offers some of Bornholm's richest wreck diving. Water ranges 3-18°C, warmest July, August, September.
Erna, a schooner, sits in just 3 metres of water off Bornholm. This is a shallow, easy dive, perfect for newer divers or those looking for a relaxing dip. You’ll find the wreck fairly broken up, but its skeleton provides good cover for local fish. Expect to see small schools of pollock darting through the ribs and plenty of crabs scuttling over the timbers.
