Exploring the Small Group Volcano Hike with a Professional Geologist: An Honest Review

If you’re into geology, volcanoes, or just want a truly unique Iceland experience, this small group volcano hike from Reykjavik might just be your cup of tea. Guided by a knowledgeable geologist, you’ll trek across fresh lava fields, learn how new land is made, and get an up-close look at Iceland’s most recent volcanic activity.
What really draws us to this tour are the personalized experience thanks to the small group size—max six people—and the chance to learn directly from a geoscientist who can answer all your burning questions about lava, eruptions, and Earth’s fiery processes. Plus, the views from the crater are said to be breathtaking, offering a glimpse into the raw power of nature.

What You Can Expect from the Tour
This six-hour adventure begins in Reykjavik, with a short drive to the Reykjanes Peninsula, home to Iceland’s youngest lava and volcanoes. The real highlight is the hike up to Fagradalsfjall, the volcano that erupted in 2021, which has captured international attention.
We loved the way the guide starts with an introduction to Iceland’s volcanic history, setting the stage for the adventure ahead. You’ll learn about the early signs of eruptions, the recent activity, and how the composition of the lava influences the landscape. This background makes everything you see more meaningful—you’re not just walking through a lava field, but witnessing the ongoing story of Earth’s fiery creativity.
The hike itself is designed to be engaging yet manageable. Expect dirt and gravel paths, with some steep switchbacks. As one reviewer pointed out, “Giuseppe was kind and funny; when you combine that with his professional knowledge as a geologist, you have a perfect tour guide.” The guide’s pacing is considerate, allowing breaks, especially for those who might need a breather. It’s not a walk in the park, but the effort is rewarded with stellar views of the lava flows, fissures, and volcanic formations.
While glowing lava isn’t guaranteed at all times, the chance of seeing volcanic activity up close remains high, especially given the recent eruptions. Many travelers mention feeling like they are walking on the surface of another planet, surrounded by freshly cooled black rock and intricate volcanic formations.
Once at the crater viewpoint, the views are often described as “breathtaking,” with the vast lava fields stretching out as far as the eye can see. The landscape is constantly changing, and you get to see how the landscape is shaped by the ongoing volcanic activity.
We also appreciated the scenic drive back through the Reykjanes Peninsula. Along the way, you’ll pass geothermal hot springs, crater lakes, and rugged volcanic mountains. This part of the trip really completes the experience, offering plenty of chances to reflect and snap photos of Iceland’s surreal terrain.
The Value of the Experience

At $215.66 per person, this tour might seem a bit pricey, but considering what’s included—guided hike, parking fees, crampons, headlamps, and private transportation—it offers excellent value. The small group size means you’ll get more attention from your guide, which is especially valuable given the geological expertise on offer.
Many reviews praise the knowledgeable guides and the personalized attention, calling the experience “absolutely worth it” and “a highlight of their Iceland trip.” The fact that the guide is both friendly and well-versed in geology means you’ll come away with more than just photos—you’ll have a solid understanding of what you’re witnessing.
Some travelers pointed out that the hike can be challenging, especially over sharp, slippery rocks and narrow sections, so sturdy hiking boots are a must. The tour is not recommended for children under 12, largely due to terrain and physical demands, but for those with a moderate fitness level and an interest in volcanoes, it’s a rewarding challenge.
Critical Considerations

While most reviews are glowing, a few mention logistical hiccups, such as the vehicle being crowded for the ride to the trailhead—something to keep in mind if you prefer more space. Also, weather can be unpredictable: rain, wind, or cold can make the hike tougher, so dressing in layers and bringing rain gear is advised.
Another aspect is availability—this tour books up quickly, and cancellations can happen if guides are sick or weather conditions deteriorate, sometimes close to departure. One reviewer was disappointed after their tour was canceled last minute due to guide sickness, which shows the importance of flexible plans or backup options.
Who Should Consider This Tour?

This adventure is perfect for adventurous travelers with an interest in geology, volcanoes, or Earth sciences. It’s also a fantastic choice for those who enjoy active outdoor experiences and can handle moderate physical exertion. If you’re traveling with a partner or a small group of friends who share your curiosity and fitness level, you’ll likely find this highly rewarding.
However, if you’re not comfortable walking on uneven, rocky terrain or have mobility issues, this might not be the best fit. Also, those expecting to see glowing lava might need to temper expectations, as this depends on volcanic activity and lighting conditions.
