The Bjurälven karst area is located in northern Sweden. The Bjurälven cave is the longest underwater cave in Sweden. Each year a team of cavedivers explore and map the cave system

In 2016 in part of the Bjurälven Exploration cave divers explored the Dolinsjö Cave. They brought a laddeer with them to explore the roof inside “The Rain Hall”.

To explore the roof inside “the rain hall” we needed to transport a ladder inside the cave as a small part project in the expedition and it was great fun.
