Raufarhólshellir Lava Tunnel

Background

History & Background

Raufarhólshellir Lava Tunnel in South Iceland was formed through Iceland's volcanic processes, likely as a lava tube created when the outer surface of a lava flow cooled and hardened while molten rock continued flowing inside. Iceland's caves have served humans since the settlement era — archaeological evidence shows that early settlers used caves as shelters, storage spaces, and even as hiding places during times of conflict. Icelandic folklore is rich with stories about caves, often portraying them as dwellings of trolls, hidden people (huldufólk), or outlaws. Some caves, like Surtshellir, have archaeological remains dating back to the 10th century. Today, caves like this offer visitors a glimpse into Iceland's geological history and cultural imagination.

Raufarhólshellir is a large lava tube in Ölfus. The commercial Lava Tunnel experience operates from a dedicated parking and reception area reached from Route 39. The operator lists GPS coordinates N63°56.407′, W21°23.742′ and advises visitors to bring warm clothing and sturdy shoes.
