Eldvorp is a long and prominent crater row west of Grindavik on the Reykjanes Peninsula. The craters formed during a fissure eruption and follow one of the peninsula's active volcanic fracture systems. Geothermal activity is also present, with steam and hot ground occurring in parts of the area. Eldvorp is a clear example of how fissure eruptions create crater rows and lava fields in Reykjanes. Access conditions can change, so visitors should check current closures and local safety information before travelling.
