While the water might be chilly at around 1°C, the thrill of being in the presence of orcas makes it worthwhile. There are dedicated orca expeditions you can join and you also have the chance to witness the Northern Lights and spot humpback whales.

2. Ojamo Mine, Finland

Finland’s Ojamo Mine, a labyrinth of submerged tunnels with crystal-clear waters, presents a unique freshwater diving experience. Mining operations were discontinued at Ojamo in the mid-1960s, after which groundwater slowly filled the entire mine. Diving there is a mind-blowing experience and attracts cave divers from all over Finland.

The shallowest tunnel at Ojamo starts at around 28m and some tunnels penetrate for almost 2 km. There are also enormous chambers, with many tools and remnants of the mining days. Ojamo Mine can be dived all year, with a constant temperature of 4°C in the tunnels and the open water warming up to around 20 °C in summer.

3. Ice diving, Finland

Scandinavia’s icy winters offer a unique opportunity to take the plunge and go ice diving. There are lots of places to go ice diving throughout Scandinavia including in Finland. The Ojamo Mine is popular for ice diving, as is Lake Päijänne, the second-largest lake in Finland. The UNESCO Rokua Geopark near Oulu is also a great choice, with numerous features to explore besides the main body of water.

Descend into the depths of Sognefjord to discover one of the world’s best wreck dives, the DS Frankenwald.
