help Raufarhólshellir FAQ
How old is Raufarhólshellir lava tunnel?
Raufarhólshellir formed during the Leitahraun eruption around 5,200 years ago. Lava continued moving beneath a cooling crust, leaving a tube approximately 1.3 kilometers long.
Can you explore Raufarhólshellir without a guide?
Commercial visits are organized as guided tours with installed walkways and lighting in the accessible front section. The standard experience lasts about an hour, while longer options may enter rougher parts of the tube.
What are the holes in the roof of Raufarhólshellir?
They are skylights created where portions of the lava-tube roof collapsed. Sunlight and snow enter through these openings, and winter conditions can produce striking ice formations near the entrance.
How far is Raufarhólshellir from Reykjavík?
The tunnel lies beside Route 39 roughly 30 kilometers from central Reykjavík. It is therefore a much shorter excursion from the capital than South Coast caves near Vík or Vatnajökull.
