Surtshellir
Historic lava cave in the Hallmundarhraun lava field, west Iceland. One of Iceland's longest lava tubes at 1.9 km. Medieval outlaws used it as a hideout - some artifacts remain. Open to explore but challenging - ice formations near entrance, rough terrain, total darkness. Come prepared or not at all. The historical aspect adds interest beyond geology. Imagine hiding from Viking-age authorities in this darkness.
