Raufarhólshellir Lava Tunnel
Raufarhólshellir
One of Iceland's longest and most accessible lava tubes, formed about 5,200 years ago. Inside you can see colorful lava layers and shafts of light from the skylights.
Raufarhólshellir is about 1,360 m long and formed in a volcanic eruption some 5,200 years ago. Walkways and lighting have been installed inside, and entry is only with a guided group. A standard tour lasts about an hour. In winter, glistening ice columns and stalagmites form near the entrance, and light falling through the skylight makes it a great spot for photos. It is beside Route 39, about 30-40 minutes' drive from Reykjavík, and is often combined with the Golden Circle or Hveragerði. Advance online booking is required. The inside is about 0-5°C, so wear non-slip shoes.
