More than just scratching the surface during your Icelandic experience, this cave adventure is surely off the beaten path. In the winter time a lot of ice forms in the forward section of the cave and almost every stone is coated with a thin crust of ice, which makes it hazardous to walk around the cave.

Raufarholshellir lava tube cave is one of the better known lava caves in Iceland and it is easily accessible. The length of the tube is estimated to be 1360 metres. There are four entrances, all in easy reach of each other. The cave is partially collapsed and is difficult to trek, except for the innermost part which is easier because little has broken from the ceiling.
During the winter time a lot of ice forms in the forward section of the cave and almost every stone is coated with a thin crust of ice, which makes it hazardous to walk around the cave.
In the backward section, the cave forks into 3 tunnels, the lava flow from those tunnels probably joined in the Raufarholshellir cave 5000 years ago. Lava falls and other spectacular lava formations can be seen deep in those tunnels.
There are large chambers in Raufarholshellir lava tube, the largest chamber in Iceland, excluding those in Surtshellir and Vidgelmir lava tubes in Hallmundarhraun lava fields in western part of Iceland. The walk around the cave is an exciting journey and there are many things to see.
There’s a road leading to the cave’s entrance and it’s accessible all year round. It takes about an hour to reach the cave from Reykjavik in a car, and the trek through the cave itself takes about four hours. So it is probably best to plan 5-6 hours for the whole tour.
Lava tubes are natural conduits through which lava travels beneath the surface of a lava flow, expelled by a volcano during an eruption. They can be actively draining lava from a source, or can be extinct, meaning the lava flow has ceased and the rock has cooled and left a long, cave-like channel.
Lava tubes are formed when an active low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Tubes form in one of two ways: by the crusting over of lava channels, and from flows where the lava is moving under the surface.
