An Inside Look at the Tour

The Itinerary and What to Expect

From the moment you’re picked up from your Reykjavik hotel (or nearby bus stop), the tour sets a relaxed tone. The transportation is included, with pickup times varying slightly depending on the season—roughly between 12:45 and 14:00, so check your specific slot. The group size is small—max 8 people—which helps the guide give personalized attention and keep the atmosphere cozy.

Once you arrive at the site, your guide will gear you up with a helmet and a headlamp, so you’re ready to explore the dark, mysterious tunnels. The cave itself, Leidarendi, is about 900 meters long, with roughly 150 meters of walking involved. The path is circular, so you’ll mostly go down into the lava tubes and then come back out the way you went in.

The cave’s interior is packed with incredible lava formations like stalactites and drip stalagmites, which are formations created over thousands of years as lava cooled and solidified in unique shapes. “Magnificent lava formations,” as one reviewer put it, really do look otherworldly—some resemble frozen waterfalls or alien sculptures. As you navigate through narrow sections, you may need to hunch or crawl, but overall, the access is designed to be manageable for most.

Touching Ancient Lava and the Geological Wonders

One of the highlights is being able to touch and see lava that’s more than 2,000 years old. It’s a rare chance to physically connect with the volcanic history of Iceland, making the experience stand out from typical sightseeing. The guide will share insights into how these lava flows formed and cooled, adding an educational touch to the adventure.

The Guide’s Role and the Experience Atmosphere

The reviews highlight how knowledgeable guides elevate the tour—one even describes the guide as knowing “as a geologist.” Expect a lot of interesting facts about the volcanic activity that shaped Iceland. The guides also help ensure safety and make the experience enjoyable, especially if you’re new to caving.
