Step into one of Iceland’s longest and most famous lava tubes, just 30 minutes from Reykjavík. Raufarhólshellir was formed during the Leitahraun eruption over 5,200 years ago. On this guided tour, you’ll walk in the path of ancient lava and experience the raw power of volcanic forces beneath the earth’s surface.
The tunnel is naturally rugged, filled with large rocks and uneven terrain. To make your journey comfortable, footbridges and walkways have been built across the roughest areas, making the tour accessible for most visitors. Stunning lighting highlights the tunnel’s vivid colors and dramatic formations, bringing to life the story of its fiery creation.
Each tour lasts 55–60 minutes and runs every hour between 10:00–17:00. Helmets and lights are provided. We recommend wearing sturdy shoes, warm clothing, and a waterproof jacket, as water often drips from the ceiling.
The lava tunnel stretches 1360 meters (4500 ft) in total, with the main passage running 900 meters (3000 ft) long. The ceiling reaches up to 10 meters high, and at the entrance, collapsed sections let daylight stream in, forming three striking columns of light. Inside, you’ll find breathtaking lava formations, lava falls, and—during winter—ice sculptures that add to the tunnel’s otherworldly atmosphere.
The Lava Tunnel is less than 30 km from Reykjavík and is accessible year-round by all vehicles.
