Diving in Sweden

Dive the Swedish Baltic Sea and discover all 10,000 shipwrecks at the bottom!

Best time: April–December


Due to its low temperatures, diving in the Baltic might not sound too exciting. Moreover, marine life here is not as colourful as it is in the Red Sea, for example. However, diving off the Western coast in Sweden is one of the most rewarding experiences. There are around 10,000 registered shipwrecks which are very well-preserved in the low salinity of the Baltic Sea. The area of Väderöarna is where you can find most of the biodiversity due to the higher salt levels. There are more than 20 spec​​ies of nudibranchs, both soft and hard corals, and plenty of fish and lobsters.
