Hálsanefshellir

Hálsanefshellir is a sea cave located on the southern coast of Iceland. It is situated in the vicinity of the village of Vík í Mýrdal and is a popular natural attraction for tourists visiting the area. The cave is formed by erosion from the powerful waves of the North Atlantic Ocean. Its name, Hálsanefshellir, translates to "neck nose cave" in Icelandic, likely referring to its distinctive shape and location.

The cave is known for its impressive basalt columns, which are a common geological feature in Iceland, formed by the slow cooling of lava flows. Visitors can access Hálsanefshellir during low tide, as it is partially submerged during high tide. The floor of the cave is typically covered in dark sand and pebbles. The entrance to the cave offers views of the Reynisdrangar sea stacks and the black sand beach of Reynisfjara.

Due to its coastal location, Hálsanefshellir can be subject to strong winds and unpredictable wave patterns. Visitors are advised to exercise caution and check tide times before entering. The cave is part of the larger geological landscape of the region, which is characterized by volcanic activity and dramatic coastal formations. It is a site that showcases the ongoing erosional forces shaping the Icelandic coastline.
