Przewodnik turystyczny — Arnarker

Arnarker is a 515 m (1,693 ft) long cave in the Leitarhraun lava field, north of the old road leading from Þrengsli towards Selvogur. 

Explore this area while on a self drive tour in Iceland.

Although its original name is Arnarker (Eagle's Basin), the cave is almost always locally referred to as "Kerid". It takes about an hour to drive from Reykjavik to Arnarker and a marked path leads to it from a sign by the road. 

Arnarker is spacious, wide and high, although the cave’s northern section is severely damaged; its ceiling collapsed a few thousand years ago and deposits cover the floor, except for the first 100 metres, which are perpetually covered by a thick sheet of ice. In late winter, enormous icicles form inside the cave, some becoming well over 3 m (10 ft) long.
