Raufarhólshellir, one of Iceland’s largest and most accessible lava tunnels, offers a remarkable glimpse into the island’s volcanic history. Located just 30 minutes from Reykjavík, this lava tube, formed during a volcanic eruption approximately 5,600 years ago, provides visitors a unique opportunity to explore a subterranean world shaped by molten lava.
Known for its striking geological features and impressive scale, Raufarhólshellir is a must-visit destination for anyone interested in Iceland’s volcanic landscape.
Formation of the Lava Tunnel
Raufarhólshellir, like many other lava tubes in Iceland, was formed during a volcanic eruption when lava flowed from the Leitahraun eruption. As the surface of the lava flow cooled and solidified, molten lava continued to flow underneath, creating the hollow tube that exists today.
This tunnel stretches over 1,360 meters (4,460 feet), making it one of the longest lava tubes in Iceland. At points, the tunnel reaches impressive dimensions of 10 meters (33 feet) in height and up to 30 meters (98 feet) in width, making it spacious enough to walk through comfortably.
The Experience of Visiting Raufarhólshellir
Raufarhólshellir is now equipped with a well-constructed walkway and lighting, making it accessible to visitors of all ages and fitness levels. Walking through the tunnel, you will notice fascinating lava formations, including stalactites and stalagmites made from dripping lava. The tunnel also has multiple skylights, or openings in the ceiling, which allow natural light to stream in and highlight the colorful rock formations inside.
One of the most striking features is the seasonal ice stalagmites that form during the winter months, adding another layer of visual wonder to the cave. Visitors can see the layers of different lava flows marked on the walls, showcasing the different stages of volcanic activity.
Guided tours of the tunnel provide valuable insights into the geological processes that shaped it, as well as its historical significance. It’s also worth noting that Raufarhólshellir has been used as a filming location for both movies and TV shows, including the 2014 film Noah and the series Sense8.
Protecting Raufarhólshellir for Future Generations
Due to its popularity and proximity to Reykjavík, Raufarhólshellir has seen significant foot traffic over the years, which led to damage before the introduction of guided tours. Prior to 2016, the tunnel was freely accessible, resulting in the destruction of many delicate lava straws (fragile lava formations that hang from the ceiling). Since then, the cave has been restored, with tons of trash removed, and access is now limited to guided tours to preserve its natural beauty.
Exploring Other Lava Tubes in Iceland
While Raufarhólshellir is one of the most famous lava tunnels in Iceland, there are several other lava tubes worth exploring:
Vatnshellir Cave: Located in Snæfellsnes Peninsula, this 8,000-year-old lava tube offers a mystical underground experience, with its dramatic twists and turns leading deep into the earth.
Leidarendi Cave: A shorter lava tunnel near Reykjavík, Leidarendi offers an equally fascinating look into Iceland’s volcanic history, with its intricate formations and smaller-scale accessibility.
Nearby Attractions: Viti Crater and the Askja Trail
While exploring the volcanic wonders of Iceland, you may want to venture further to other natural attractions like Viti Crater, an impressive volcanic crater in the Askja caldera. Known for its turquoise-colored geothermal lake, Viti is a stunning example of the island’s geothermal activity.
Additionally, hiking the Askja Trail offers a challenging but rewarding adventure through one of Iceland’s most remote volcanic areas. The trail takes hikers through lava fields, past craters, and offers incredible views of the Icelandic highlands.
