Meeting Point and Transportation
The adventure begins at the BSÍ Bus Terminal in Reykjavik, a well-known central location. From there, you’ll hop aboard a carbon-neutral transfer bus—a smooth, eco-friendly ride to the lava cave. The bus is described as a “Flying Bus” with multiple small logos, so keep an eye out and ask the driver if you’re unsure. Most travelers find the pickup straightforward, though a few mention that it’s helpful if instructions are clearer in advance.
The bus ride itself takes about 30 minutes, giving you a chance to relax and maybe snap some photos of Iceland’s scenic countryside. The journey is part of the appeal, as the views outside the window are often praised for their beauty.
Arrival and Cave Entrance
Once at Raufarhólshellir, you’ll meet your guide, who’ll provide safety equipment—helmet and flashlight—and brief you on the cave’s features and safety procedures. The cave itself is a giant lava tube, roughly 30 meters wide and 10 meters high near the entrance, with some sections of the ceiling caved in, creating columns of natural light.
The interior of the tunnel is a colorful palette of mineral deposits, with hues of orange, yellow, and deep reds. The stalactites, stalagmites, and other formations are illuminated by sunlight streaming in from the entrance, making for some truly striking photos. Several reviews mention how mesmerizing the colors are, caused by different mineral types in the rock.
The Guided Walk
The guided portion lasts about one hour. Walking through the tunnel, your guide will explain how volcanic activity created this underground landscape. You’ll learn about the geological processes that shaped the cave—and see the impressive natural features that have formed over thousands of years.
Many visitors appreciate the knowledgeable guide, who not only shares facts but also makes the experience engaging. According to reviews, guides are friendly, informative, and add a fun element to the walk. One review said, “The guide was very informative and fun,” which captures the general sentiment.
Cave Conditions and Experience
The terrain inside the tunnel isn’t overly rugged, but there are uneven rocks and some slippery sections, especially near the entrance where the ceiling has caved in. Walking poles are provided and are highly recommended—if you have mobility concerns, you might find this part challenging.
The interior is dark and cool, so dressing warmly and wearing sturdy footwear is essential. Some travelers noted that the cave’s interior can be a bit uneven and slippery, so caution is advised, especially in winter or wet conditions.

Post-Tour and Return

Some reviews suggest that the short duration might leave you wishing for more exploration, but most agree it’s a worthwhile glimpse into Iceland’s volcanic history.
The Value of the Experience

When evaluating the $120 price tag, consider what’s included: transport, a guided tour, safety equipment, and a unique inside look at a natural lava formation. Many reviewers feel that the guidance and the scenery justify the cost, especially since the tour provides a hassle-free way to see a significant geological site.
However, a few mention that the limited exploration time and the fact that only a small part of the lava tube is accessible makes the experience feel somewhat brief. One reviewer said, “Only about 0.4 km of the 1.4 km long cave is explored,” which might be a disappointment if you’re craving a more extensive adventure.
Still, for most, the combination of accessibility, natural beauty, and educational value makes this a solid choice for those wanting to understand Iceland’s volcanic roots without too much physical strain.
