This southern corner of Iceland is known for two things: the hot-tempered volcano of Eyjafjallajökull which grounded European flights back in 2010 and Seljalandsfoss – the unspoiled 40-metre-high waterfall flanked by emerald green surrounds. The gush of water is fed by the melting of nearby glacier from the very same volcano and visitors can wander around its entirety, sheltered by a rocky ridge.
