Arnarker

Arnarker, often simply referred to as Kerið, is a beautiful and fascinating lava cave located in the Leitarhraun lava field. This vast area is home to numerous lava caves, many of which extend over 500 meters in length. Arnarker stands out in particular due to its dramatic entrance, where visitors descend approximately 16 meters down into the cave.

Inside the cave, two main routes can be explored. The passage leading south is around 100 meters long, while the northern route stretches for about 400 meters into the lava field. The terrain inside the cave is mostly easy to traverse and partially vegetated, making it accessible for most visitors, although there is one section in the longer passage where the ceiling becomes noticeably low.

Access to Arnarker is straightforward. Travelers drive through the Þrengslin mountain pass from Reykjavík, and once descending from the pass, turn right at the first junction. From there, it is approximately a 5-kilometer drive to a signposted turnoff leading to Arnarker.

The surrounding area offers several interesting attractions. Nearby is Búri, another lava cave in the same region, as well as the well-known Raufarhólshellir, one of Iceland’s most accessible lava tunnels. Visitors can also enjoy recreational activities such as the disc golf course in Þorlákshöfn or relax at the Þorlákshöfn swimming pool. The coastal town of Þorlákshöfn provides various services, while the nearby camping site and scenic walks around the Þorlákshöfn lighthouse make the area well worth exploring.
