What is Raufarholshellir?
Raufarholshellir is the fourth-longest lava tube in Iceland and stretches an incredible 1,360 meters (4,460 feet), offering visitors a breathtaking glimpse into Iceland's volcanic past.
Formed around 5,200 years ago during the Leitahraun volcanic eruption, this lava tube was created when lava flowed beneath the surface, with its outer layers cooling and solidifying while molten lava continued to flow. What sets Raufarholshellir apart from other lava tunnels is its sheer size.
With heights reaching up to 10 meters (33 feet) and widths of up to 30 meters (98 feet), it's one of the most spacious lava tubes in Iceland.
Geological Significance
The Raufarhólshellir lava cave holds immense geological significance, offering a vivid display of Iceland's volcanic history. Its colorful rock formations are a result of mineral deposits left behind by cooling lava, creating a striking visual landscape.
What makes the cave truly special are the skylights, where parts of the ceiling have collapsed, allowing natural light to stream into the cave. These skylights not only enhance the cave's beauty but also provide a unique perspective on its formation process.
Inside the cave, you'll find stalactites that have developed over time, formed by mineral-rich water dripping from the ceiling and leaving deposits as it evaporates.
