Inside the Volcano: Small-Group Tour and Lava Field Hike

Inside the Volcano: Small-Group Tour and Lava Field Hike

Imagine standing at the edge of a volcano, then getting the chance to descend into its vast magma chamber—a truly offbeat adventure you won’t find on any typical bus tour. For around $450, you’ll spend roughly 5 to 6 hours with a small group exploring Thrihnukagigur, a dormant volcano just outside Reykjavík. Led by a knowledgeable guide, this experience combines a scenic drive, a rewarding lava field hike, and the thrill of descending inside a volcanic crater.

What we love about this tour is how it balances adventure with education. First, there’s the chance to hike through craggy lava fields—rocks formed by volcanic activity thousands of years ago—and then transfer into the volcano’s interior via a specialized open cable elevator. It’s a rare opportunity to stand inside a completely sealed magma chamber—a natural wonder that feels more like a scene from a fantasy film than reality. Plus, the delicious lamb soup served afterward adds a comforting finish to a day full of surprises.

The one consideration to keep in mind is the moderate physical exertion involved. The hike covers about 3 km (roughly 2 miles) across uneven volcanic terrain, which might be challenging for some travelers, especially in unpredictable weather. Also, this tour isn’t suitable for children under 8 or anyone with mobility issues. We suggest packing good hiking shoes and warm, waterproof clothing to stay comfortable throughout.

This tour is best suited for outdoor lovers, geology buffs, or anyone craving a truly unique Icelandic experience. Reviewers frequently mention how memorable and visually stunning it is, making it perfect for travelers looking for a meaningful adventure beyond the typical sightseeing.

A Detailed Look at the Tour Experience

Starting Off: From Reykjavík to Blue Mountains

The adventure begins with a pickup from your Reykjavík hotel, setting a comfortable tone for the day. As we left the city, the landscape quickly changed from urban buzz to rugged volcanic terrain. Our guide, Jonas, provided a lively introduction about the geology and history of Thrihnukagigur, informing us that this volcano last erupted about 4,000 years ago.

The drive itself is picturesque; the Blue Mountains (Bláfjöll) form a dramatic backdrop for the upcoming exploration. These peaks aren’t just scenic—they’re part of the story, as they cradle the volcano and add to the otherworldly feel of the landscape. We loved the way the guide’s stories deepened our understanding of Iceland’s fiery geological history.

Lava Field Hike: An Up-Close Look at Iceland’s Volcanic Past

Arriving at the base of the volcano, the first task is a moderate 2-mile (3 km) hike across ancient lava fields. The terrain is rugged and uneven, with sharp rocks and fissures that hint at the volcano’s violent past. The hike offers awe-inspiring views of volcanic cones and steam vents, making it clear this is a landscape shaped by fire and ash.

While demanding, it’s a manageable walk—especially if you have good hiking shoes. Reviewers like Lesley D. remarked, “It was really amazing. Totally worth it. The weather was crazy windy and raining, and we still had an amazing time.” That’s typical of Icelandic adventures: unpredictable weather shouldn’t deter you, because the scenery is worth every step.

Gearing Up: Descending into the Volcano

Once at the crater rim, safety instructions are briefed, and everyone gets helmet and harnesses. The highlight is the open cable elevator that lowers a handful of visitors into the chamber. This isn’t your average elevator—imagine a metal cage that gently takes you down 120 meters (400 feet) into the Earth’s crust.

The descent offers breathtaking views of the crater walls, vividly colored from mineral deposits that have settled over thousands of years. As Lucy R. put it, “Descending into a dormant volcano is definitely a once-in-a-lifetime experience! It’s hard to describe how beautiful and complex the rock formations are.” The interior of the volcano feels surreal—massive, silent, and painted in shades of reds, yellows, and browns, remnants of magma that cooled and solidified.

Inside the Chamber: A Natural Masterpiece

Once at the bottom, your guide leads a guided exploration of the magma chamber. The interior is a massive, open space—a natural cathedral—where the walls are still scalded from volcanic activity. The tall rock domes and colorful mineral stains evoke a sense of wonder.

Participants often comment on how unbelievably beautiful and alien the chamber looks. “The colors made the volcano a work of art,” said JoAnne S. It’s easy to forget you’re inside a natural formation created by volcanic eruptions thousands of years ago. The guide shares stories about the last eruption, helping us imagine what this chamber must have looked like when it was filled with molten magma.

Return and Reflection: Lava Fields and Final Views

After about an hour inside the chamber and exploring the surrounding area, you’ll ascend back in the cable elevator. The hike out across the lava fields offers more chances to spot steam fumaroles and volcanic cones—the landscape’s silent witnesses to Earth’s fiery power.

The drive back to Reykjavík is relaxed, letting you unwind and reflect on an experience that’s both educational and awe-inspiring. Many reviewers, like Pamela V., mention how the scenery and the inside of the volcano left lasting impressions: “Incredible experience! The colors and the size are hard to describe, and the guides made it feel safe and exciting.”

Price and Value Analysis

The $449.78 per person fee covers transportation, expert guidance, safety gear, and the once-in-a-lifetime descent into the volcano. Considering how unique this activity is—being in the only place in the world where you can actually enter a sealed magma chamber—the cost is justified for many travelers.

Most reviews highlight that the tour offers excellent value for what you experience. The opportunity to walk through lava fields, learn from knowledgeable guides, and see inside a volcano makes it stand out from typical Iceland excursions. Plus, the lamb soup and refreshments add a cozy, satisfying touch after the outdoor adventure.

The tour is often booked about 101 days in advance, which signals how popular and well-regarded it is. For those who love geology, adventure, or simply want a unique story to tell, this tour is a solid investment.

Practical Tips for Travelers

• Wear good hiking shoes: The terrain is uneven and rocky, so sturdy footwear is essential.
• Dress warmly and waterproof: Iceland’s weather can be unpredictable—think layers, waterproof jackets, and gloves.
• Be in moderate physical shape: The hike is moderate but involves up to 7 km across difficult terrain.
• Age minimum is 8: The activity isn’t suitable for very young children or those with mobility issues.
• Expect some waiting: The safety briefing and gear-up take extra time, so arrive prepared.
• Book early: Due to high demand, booking several months ahead is wise.

The Sum Up

This tour offers a rare blend of adventure, education, and natural beauty. The highlight—descending into a volcano’s magma chamber—feels like stepping into an untouched world. The lava field hike provides a tangible connection to Iceland’s volcanic past, while the small-group setting ensures a more personal experience.

It’s best suited for outdoor enthusiasts, geology lovers, and curious travelers looking for a day full of stunning scenery and memorable moments. The value lies not just in the sights but in the stories you’ll carry home, the sense of accomplishment after a challenging hike, and the visual feast inside the crater.
