Plura Norway

Plura Cave, also known as Pluragrotta, is a cave system located in Rana, Norway. It is the deepest cave in Northern Europe, with a maximum depth of over 130 meters. Plura Cave is a popular destination for experienced cave divers, despite its dangers. The cave’s passages were formed by the flow of the Plura river over limestone, and the cave system includes marble formations. A number of species have been identified in the cave ecosystem. The cave is known for its stunning sea walls and several caves and tunnels, some of which lead to the open sea. The cave is also filled with long, colorful passages that are admired by diving hobbyists. However, the cave’s narrow and difficult passages, ice-cold, pitch-black water, and sharp edges make it extremely dangerous even for the most experienced cave divers in the world. The extreme depth of the cave, freezing temperature of the water, and dark and narrow sections can damage dry suits and disorient divers
