Why dive here
With 66+ marine species recorded in the area - including jellyfish lake - Opalsoen offers some of Bornholm's richest diving. Water ranges 3-18°C, warmest July, August, September.
Opalsoen, on Bornholm, offers a dive into a flooded quarry. Expect freshwater conditions and a distinct lack of coral, but it’s an interesting change of pace from coastal dives. It's a good spot for divers looking for something different, particularly those interested in inland diving or honing their buoyancy skills in calm conditions. We've heard there are some interesting rock formations to explore, and it's generally quite sheltered from the elements.
Safety Notes
Cold water this month (avg 14°C). Drysuit or thick wetsuit (7mm+) recommended.
