One of the south coast’s most recognisable natural formations is the rocky plateau and huge stone sea arch at Dyrhólaey (deer-lay), which rises dramatically from the surrounding plain 10km west of Vík, at the end of Rte 218. The promontory is a nature reserve that's rich in bird life, including puffins. It’s closed during nesting season (15 May to 25 June), but at other times you can visit its crashing black beaches and get awesome views from atop the archway.
The archway itself, is best seen from Reynisfjara.
According to Njál’s Saga, Kári – the only survivor of the fire that wiped out Njál’s clan – had his farm here. Another Viking Age connection is the cave Loftsalahellir , reached by a track just before the causeway to Dyrhólaey, which was used for council meetings in Saga times.
