Guided tours provide insights into the tunnel’s formation and significance in Icelandic geology, offering a unique opportunity to explore the raw power of volcanic forces beneath Iceland’s surface.

A typical lava tunnel in Iceland is a geological formation created by the solidification of lava after a volcanic eruption. These tunnels can vary in size and shape but often feature long passages with unique rock formations, such as stalactites and stalagmites, formed by the cooling and solidification of lava over time. 

How Was Raufarhólshellir Lava Tunnel Formed

The birth of Raufarhólshellir can be traced back to a volcanic eruption, specifically from the Leitahraun flow, which occurred roughly 5,200 years ago. As the molten lava advanced across the terrain, the top layer cooled and solidified while the underneath remained fluid and continued to flow.

Over time, this process created a hollow passage, encapsulating a section of the once-flowing lava river, which is now one of the longest lava tubes in Iceland.

Volcanic activity in Iceland is pivotal to the island’s ever-changing geography. The formation of Raufarhólshellir stands as a direct consequence of such activity, revealing the dynamic forces at play beneath Earth’s crust.

The walls of the tunnel exhibit layers of volcanic rock, a testament to the powerful eruptions that have shaped the region. Exploring its spacious interior allows you to visually witness the impact of these geological forces, as they’ve molded the tunnel’s unique features.
