Bjarnagjá is a lava ravine located on the Reykjanes Peninsula in Iceland, formed by tectonic activity where continental plates shift. The site features a rift that reaches depths of approximately 18 to 20 metres. Divers access the water directly from the shore. The environment consists of a mix of fresh groundwater and seawater, creating a unique brackish habitat. While specific species are not confirmed at this location, the habitat supports general temperate freshwater and brackish life forms. Water temperatures fluctuate between 5C and 11C throughout the year, requiring appropriate thermal protection for all divers.
