Book NowStory & Folklore
Gíslahellir is one of Iceland's fascinating cave systems, formed thousands of years ago by volcanic activity. As lava flowed across the surface and the outer layers cooled and hardened, molten rock continued to flow beneath, eventually draining to leave hollow tubes and caverns. These lava tubes are found across Iceland and are among the most accessible in the world.
