The lava tunnel at Raufarhólshellir near Reykjavik was created by the volcanic eruption Leitahraun about 5200 years ago. The tunnel is the longest and most famous lava tunnel in Iceland. The lava tunnel is impressive 1360 meters long. The main tunnel, which we use, is 900 meters long. On our extreme tour we go all the way to the bottom of the main tunnel.
