An Adventurous Day Inside a Volcano

This tour strikes a perfect balance between adventure, education, and natural beauty. We love how it transforms a typical sightseeing day into something more immersive. From the moment you’re picked up from your Reykjavik hotel, you’re whisked away with a small group (max 18 people), ensuring a more personalized experience. The drive to the Blue Mountains is scenic, with your guide sharing insights about Iceland’s volcanic past, building anticipation for what’s ahead.

The Blue Mountains (Bláfjöll) set the dramatic stage for your volcanic journey. These rugged peaks are not just beautiful—they’re the gateway to the Thrihnukagigur volcano. We appreciated how the guide explained the volcanic formation happening 4,000 years ago, giving context to the geological marvel you’re about to see. The landscape is stark, almost alien, with sharp cones, fissures, and steaming gas vents.

The Moderate Hike & Scenic Lava Fields

A core part of this experience is the 2-mile hike across lava fields. Reviewers like Lucy note, “The walk was very enjoyable, and the scenery was surreal.” The terrain is uneven and rocky, so sturdy hiking shoes are essential. The landscape is dotted with volcanic cones and fissures that make for incredible photo opportunities and a chance to connect with Iceland’s fiery underground forces.

The walk, rated as moderate, offers plenty of opportunities to stop and take in the views or listen to the guide’s stories about recent eruptions, magma flows, or oddities like steaming fissures. Some reviewers mention windy or rainy weather, which can make the trek more challenging but also adds to the adventure. As Lesley notes, “Despite crazy windy and rainy weather, we still had a great time.”

Preparing for the Descend: Inside the Volcano

Once at the crater’s rim, you gear up with helmets and harnesses — a process that can be quite fun, especially with a professional guide like Jonas, praised for his knowledge by multiple reviewers. The highlight is the open cable elevator that transports you about 120 meters down into the magma chamber. This is such a rare opportunity: the only place in the world where you can physically descend into a hollow volcano.

The descent offers spectacular views of the walls, which are vividly colored and textured from mineral deposits and solidified magma. Many reviewers, like Grace, describe it as “blown away,” emphasizing how the view inside is like stepping into a painter’s palette of colors and shapes.

Once at the bottom, the interior is just as mesmerizing. The tall, sculpted rock dome is dotted with mineral stains, and your guide will share stories about the last eruption, imagining the molten liquid that once filled this space. It’s a place that ignites the imagination — a geological wonder preserved for your exploration.

Exploring the Interior & Final Views

Time inside the chamber varies depending on weather and group size but generally includes plenty of opportunity to absorb the surroundings and listen to your guide’s tales of volcanic activity. Reviewers like Jane say, “The colors inside made the volcano a work of art,” and note how the experience feels like walking through a natural cathedral.

As you ascend back out of the chamber, the views from the elevator are just as striking. The entire experience—from the hike, the descent, and the exploration—is meticulously guided to ensure safety and engagement. The guides are praised for their friendliness and knowledge, making the experience comfortable and memorable.

Lava Field Walk & Return

After inside the volcano, you retrace your steps across the lava fields, which are remarkably untouched, with cones and fissures creating a raw, almost prehistoric landscape. Some, like Nelsie, highlight that “the walk was worth it, and the soup afterward was a lovely reward.” The final drive back to Reykjavik offers a chance to reflect on the day’s adventure.

Practical Details & Value

At $449.78 per person, the tour might seem steep, but it includes transportation, safety gear, expert guides, and a truly once-in-a-lifetime experience. The small-group setting ensures plenty of personalized attention, and reviews repeatedly mention the guides’ knowledge and friendliness.

The 5 to 6 hours duration is well-spent, offering enough time to fully enjoy each part of the journey without feeling rushed. The tour is recommended for ages 8 and up, with a moderate fitness level required due to the hike and uneven terrain.

It’s worth noting that weather can influence the experience, and tours may be canceled or rescheduled in poor conditions. But, according to reviews, the guides are transparent and accommodating, offering rescheduling or refunds if needed.

Authentic Experiences & Reviewer Insights

Many reviews highlight the guides’ skillful storytelling and their ability to keep everyone safe while making the adventure fun. Jonas, in particular, earned praise for his knowledge and helpfulness. Reviewers repeatedly mention the stunning visuals inside the volcano — the mineral-stained walls, the towering dome, and the colors that make the chamber feel like a natural art installation.

Several reviewers also mention enjoying the lamb soup served afterward, a cozy, hearty touch that caps off the day. The food, along with the safety gear and transportation, adds to the overall value of the trip.

One reviewer even saw an Arctic fox during the lava field walk, which underscores how this tour immerses you in Iceland’s wild and rugged landscape.
