The Lava Tunnel, known as Raufarhólshellir, is one of Iceland’s most impressive and easily accessible lava caves, located just 30 minutes from Reykjavik. Formed during a volcanic eruption around 5,200 years ago, this massive tunnel stretches for about 1,360 metres (4,460 feet), making it one of the longest lava tubes in Iceland. Visitors to Raufarhólshellir can explore the stunning underground world created by flowing lava, which left behind intricate rock formations, vibrant mineral deposits, and fascinating patterns on the cave walls.
Guided tours of The Lava Tunnel provide an unforgettable experience, leading visitors through sections of the cave where the ceiling has collapsed, allowing natural light to illuminate the interior. In winter, the tunnel is often adorned with spectacular ice formations, adding to the surreal beauty of the cave. The tour is suitable for all levels of adventurers, with options ranging from easy walks along well-lit paths to more challenging explorations of deeper sections of the cave.
Raufarhólshellir offers a unique glimpse into the powerful geological forces that have shaped Iceland’s landscape, making it a must-visit for anyone interested in the island’s volcanic history and natural wonders.
