Raufarhólshellir: Lava Falls Adventure Tour

The Raufarhólshellir Lava Falls Adventure Tour is a captivating underground journey into one of Iceland’s largest lava tubes, located in the Southern Region. At $170 per person, this 3-hour adventure is ideal for those craving a physical challenge and a rare glimpse into the volcanic forces that shaped the island. Led by knowledgeable guides from The Lava Tunnel, the tour takes you over 1.3 kilometers inside the cave, revealing visually stunning lava formations and the impressive lava falls at the cave’s source.

What we really like about this experience is the authenticity and sense of adventure it offers—there’s nothing quite like walking through a 5,000-year-old lava tube, feeling the rugged terrain beneath your feet. Plus, the small group size (max 8 people) ensures plenty of personalized attention and a more immersive experience. The highlight for many is the rare lava falls—a striking feature in only a handful of caves worldwide—and the opportunity to hike over large boulders in the dark.

One potential consideration is that this tour is physically demanding. The terrain includes big rocks, boulders, hills, and low passages, making it unsuitable for travelers with mobility issues, claustrophobia, or those who aren’t comfortable with hiking in uneven, challenging conditions. Also, you’ll need hiking shoes with ankle support and a good balance to keep safe and enjoy the experience fully.

This is a perfect choice for adventurous travelers who enjoy physical activity, are prepared for tough terrain, and want to see the raw volcanic beauty of Iceland underground. It’s especially well-suited for those who appreciate expert guides and authentic, off-the-beaten-path experiences.

Setting the Scene: Why This Tour Matters

Iceland is famous for its volcanic landscape—stunning waterfalls, glaciers, and geothermal activity. However, few experiences offer a deeper connection with the island’s fiery origins than exploring its lava tubes. Raufarhólshellir is one of the largest, and this tour elevates the experience by focusing on the most dramatic features inside the cave, notably the lava falls.

This tour is less about sightseeing from afar and more about getting your hands dirty and your boots blackened as you traverse rugged terrain. The $170 price tag might seem steep at first glance, but considering the small group size, expert guidance, and the unique nature of the lava falls, it’s a solid value for an experience that few travelers get to do.

What to Expect on the Tour

The adventure begins at the service building where you check in about 15 minutes before your scheduled start. The small-group format means you’ll be with just a handful of fellow explorers, led by a knowledgeable guide who will ensure you’re equipped, safe, and informed.

The first part of the tour involves walking into the lava tube, which is a dark, geological marvel. As you progress, your guide will explain how the lava flowed over 5,000 years ago, leaving behind fantastical formations—stalactites, stalagmites, and twisting lava walls. The colors inside are mesmerizing, with shades of black, brown, and occasional hints of orange.

As you move deeper into the cave, the terrain becomes more rugged. You’ll be hiking over large boulders, steep hills, and narrow passages. Some sections are low and may require crawling, so good hiking shoes with ankle support are essential. You’ll be navigating over uneven ground with the aid of headlamps and crampons (used in winter).

The culmination is reaching the lava falls, a rare and breathtaking feature—you might be the only few people in the world to see this in such detail. The lava falls resemble a cascading flow frozen in time, a reminder of the volcano’s power. Your guide will take time to explain the formation and answer questions, adding context to this volcanic spectacle.

The tour generally lasts 3-4 hours, depending on the group’s pace. Expect to spend most of that time underground, with the final reward being your view of the glowing, intricate lava formations at the end of the tube.

Authenticity and Guides: Why They Matter

From reviews, it’s clear that guides like Anna and Sóley make a significant difference. They’re praised for their professionalism, patience, and knowledge, bringing the cave to life with stories and explanations. Their expertise helps you navigate difficult terrain safely and appreciate the geological history behind every twist and turn.

The small groups, capped at 8 people, ensure you won’t feel rushed or lost in a crowd. It’s a more personalized experience, perfect for travelers who value quality over quantity.

Terrain and Physicality: What You Need to Know

This isn’t a walk-in-the-park tour. The terrain is challenging, with big rocks, steep hills, and low passages. Several reviews emphasize the importance of wearing proper hiking boots with ankle support, as well as being physically fit and balanced.

One reviewer mentioned that without proper footwear, you simply can’t go. “HAVE A GOOD HIKING BOOTS OR YOU WON’T GO!” they advise. The terrain is rugged enough that even those used to hiking might find it demanding, especially after a long day of sightseeing.

It’s not recommended for pregnant women, people with mobility impairments, claustrophobia, or heart problems. And because of the tight low passages, those prone to claustrophobia should think twice before booking.

The Challenge and the Reward

The most impressive feature—the lava falls—is what makes the tour stand out. Seeing a rare lava formation that’s only visible in a handful of caves around the world is a highlight. Many reviewers agree that it’s worth the effort and physical challenge.

The duration inside the cave can be up to 4 hours, so you should be prepared for a long, physically demanding experience. Yet, many found it hugely rewarding, praising the stunning views and authentic adventure.

Price and Value

At $170, this tour offers a premium experience. Compared to other underground adventures, the small group size, expert guides, and exclusive access to the lava falls justify the cost. It’s a more intimate and educational experience than larger bus tours, giving you a real sense of exploring volcanic Iceland firsthand.

While not cheap, the value is evident in the quality of the experience—the chance to explore a 5,000-year-old lava tube with guidance, safety equipment, and personalized attention makes this worth considering if you’re after a genuine adventure.
