The Lava Tunnel Tour – Raufarhólshellir

Exploring Iceland’s volcanic landscape doesn’t always mean standing atop a mountain or gazing at waterfalls; sometimes, the most unforgettable sights are hidden beneath the surface. The Lava Tunnel Tour at Raufarhólshellir offers just that—a chance to walk through one of the country’s longest and most spectacular lava tubes. For around $60, you get about an hour of guided exploration, helmets, and headlamps included, making it an easy, safe way to witness the raw power of Iceland’s volcanoes.

What we love about this experience is how accessible it is—you don’t need special climbing skills, yet you still get a close-up encounter with the geological processes that shape Iceland. The tour’s guides are knowledgeable and engaging, sharing fascinating insights about the tunnel’s formation and the volcanic activity that created it. The tunnel’s changing colors and natural formations provide a surreal backdrop that makes you feel like you’ve stepped into another world.

One potential consideration is the uneven footing inside the tunnel. While the tour is rated as easy, walking over rocky surfaces and stairs requires sturdy shoes and a bit of balance.

In-Depth Review of the Lava Tunnel Experience

What Makes Raufarhólshellir Special?

Raufarhólshellir is one of Iceland’s longest lava tubes, carved more than 5,200 years ago during the Leitahraun eruption. This naturally formed tunnel stretches nearly a kilometer, but the tour typically explores a significant section accessible and safe for visitors. Walking through it, you’ll see the fascinating aftermath of volcanic activity—massive chambers, flowing lava formations, and natural sculptures created as the lava cooled.

The tunnel’s impressive size and the way light plays off its textured walls are captivating. Several reviews mention the “incredible natural features like lava stalactites,” which resemble frozen waterfalls and otherworldly sculptures. The changing hues of the rocks—deep black, warm reds, and silvery grays—reflect how different eruptions and cooling rates have shaped its appearance over millennia.

The Guided Tour — Why It Matters

One of the standout aspects of this experience is the guide’s role. Reviews frequently praise the guides—names like Benjamin and Alex appear as memorable, witty, and extremely knowledgeable. They make the geology accessible and fun, sharing stories that turn a rocky walk into a captivating story about Iceland’s volcanic past.

The guide’s explanations about the tunnel’s formation, the types of lava flows, and even the bacteria living in total darkness (a fact that surprises many) add layers of interest. For example, the microbial life here has caught NASA’s attention due to its potential implications for life on Mars. It’s these details that elevate the tour from simple sightseeing to an educational adventure.

What to Expect During the 1-Hour Tour

The tour begins at the designated meeting point—Raufarhólshellir816—and lasts roughly an hour, including walking, listening, and exploring. You’ll be provided with a helmet and headlamp, essential gear for safety and visibility. The terrain inside the tunnel is uneven, with rocky patches, stairs, and some slopes, so sturdy shoes are a must. Warm clothing is advisable because the interior of the tunnel can be chilly—around 32°F (0°C)—even if the weather outside is mild.

The trail is designed with safety in mind, with some platforms and lighting installed to help visitors navigate comfortably. Still, the uneven surfaces mean you need to watch your step, especially if you have back or knee issues or are traveling with young children. The tour is rated as easy, but caution is wise.

The Experience Itself — A Visual and Educational Feast

Once inside, we loved the way the guide described the formations and took us to viewpoints that highlight the tunnel’s grandeur. The natural features — lava stalactites, flow marks, and the layered cross-sections of cooled lava — give you a sense of the immense forces involved in Iceland’s volcanic activity. Several reviews emphasize how “breathtaking” the visuals are, with one traveler noting it feels “like stepping into another world.”

The guide also shares stories about eruptions over 5,000 years ago and explains how the tunnel was formed as lava flowed beneath the surface. The fact that the tunnel has been incorporated with walkways and lighting makes it easier for visitors to enjoy the natural beauty without feeling overwhelmed by rough terrain.

Authenticity and Accessibility

While some caves can be difficult or require technical skills, Raufarhólshellir keeps it accessible. The relatively short duration and straightforward route make it suitable for a wide range of travelers. Families with children over 3 are generally welcomed, provided they can handle the uneven surfaces. Service animals are permitted, and bathrooms are available at the site.

Value for Money

At $60.77 per person, the tour offers a good balance of price and experience. Many reviews praise the “good value” considering the guide’s expertise and the unique opportunity to walk inside a real lava tube. The inclusion of gear and the small group size (up to 30 travelers) mean you won’t feel lost or rushed, and everyone gets a chance to ask questions.

Considerations Before Booking

The main consideration is the physical aspect—walking over uneven rocky surfaces and stairs might be challenging for some. Also, the tour lasts about an hour, so if you’re eager for a more extensive cave exploration, this might feel brief. Some reviews mention that the tour doesn’t go the full length of the tunnel, but it still covers enough to give a very worthwhile experience.
