Explore the magnificent lava tunnel Raufarholshellir, one of the longest and best-known lava tubes in Iceland. It is located just 30 minutes from Reykjavik and is easily accessed year
A journey into Raufarholshellir is a unique experience and a great opportunity to witness the inner workings of a volcanic eruption as you walk in the path of lava that flowed during the Leitahraun eruption, which occurred east of the Blafjoll mountains about 5200 years ago. Every winter spectacular ice sculptures form inside the entrance of the cave, making the experience of visiting the lava tunnel even more breathtaking.
The total length of the tunnel is an impressive 1360 m (4500 ft), the main tunnel being 900 m (3000 ft) long. The tunnel is up to 30 m (98 ft) wide with headroom up to 10 m (32 ft) high, making it one of the most expansive lava tunnels in Iceland.
Our standard tour allows you to explore the tunnel in an easy and enjoyable manner. A footbridge has been built, and impressive lighting in this part of the tunnel highlights the changing colors and clearly shows the powerful volcanic activity that formed the tunnel.
Helmets and lights are provided. Warm clothes and sturdy shoes are recommended. There is usually some water dripping from the ceiling, so wearing a water resistant or waterproof jacket/clothes is also recommended.
