The Lava Tunnel is one of the longest and best explored lava tubes in Iceland. It is located about 30 minutes from Reykjavík and can be visited all year round. With appr. 1.4 km in length, 30 m in width and a height of 10 m, the tunnel is thousands of years old. During a guided tour through the lava tunnel you will learn how the cave was formed by a volcanic eruption over 5,000 years ago and how the lava made its way through the plain in southwest Iceland.
How to get there
The Lava Tunnel is a 30 minutes' drive outside of Reykjavík. The roads are usually passable even in winter. If you participate in one of the tours through the tunnel, you can book a bus transfer from and back to Reykjavík.
