What to Expect from the Tour

This trip starts with a pickup or meeting point in Reykjavik, followed by a roughly 45-minute bus ride to the base camp near the volcanic site. The journey begins with a moderate hike across a landscape that looks like it belongs on another planet — a vast, hilly lava field. This part of the experience is what really sets the tone; it’s scenic, a little rugged, and offers plenty of photo opportunities.

The hike to the crater takes approximately 45-50 minutes, with some uneven terrain and gentle inclines. Guides do a great job explaining the volcanic activity, helping you appreciate the geological significance of the area. When you arrive at the crater, you’ll receive a safety briefing and gear, including helmets and harnesses, before the descent.

The descent into the volcano chamber is about 10 minutes. You’ll be lowered into the chamber via a lift, which is a highlight for many. Inside, you’ll have up to an hour to explore the chamber’s vibrant colors and patterns formed by mineral deposits — a truly surreal landscape. The interior is accessible with expert guides at all times, ensuring safety and comfort.

After your time inside, the guides will help you ascend back to the surface and then enjoy a well-deserved meal — typically a hearty Icelandic meat or vegetarian soup, along with hot drinks. This warm-up at the end is a thoughtful touch that many reviews mention as a highlight, especially after braving Iceland’s sometimes harsh weather.

The Scenic Hike and the Lava Field

The walk across the lava field is a core part of the experience. Travelers say it’s “like walking on the surface of the moon,” with bumpy, uneven terrain and striking volcanic formations. It’s a moderately difficult hike, but not overly challenging, with straightforward paths and limited elevation gain. Still, sturdy hiking shoes are a must — sneakers and jeans just won’t cut it.

This part of the tour is about more than just the physical activity; it’s about connecting with Iceland’s volcanic landscape. Many reviews praise the views, often mentioning how breathtaking and otherworldly the scenery is. One reviewer commented, “The drive and walk to the base camp were great, and I appreciated the guide’s pride in Iceland’s volcanoes.”

Inside the Volcano: Colors, Views, and Feelings

The real star of the tour is the interior of the volcano. After descending the lift, you’ll step into a chamber filled with vibrant mineral deposits, casting the space in shades of red, yellow, and green. Some reviews describe it as “like stepping into a painting,” and others note the colors and patterns are something you can’t see anywhere else.

You’ll have about an hour inside, which is enough time to take plenty of photos, soak in the view, and marvel at the rarity of the experience. Guides are very attentive and knowledgeable, sharing insights about volcanic activity and geology, which enhance the awe of the setting. Several travelers, including one who called it “an absolute must,” raved about how surreal and spectacular the chamber was.

The Guides and Group Experience

One thing consistently praised in reviews is the guides. They are described as friendly, knowledgeable, safety-focused, and good at keeping the group on time without rushing. Some reviews mentioned guides as “entertaining and safety-minded,” which is a big deal when you’re dealing with heights and uneven terrain.

Group sizes are small — typically 4-5 people — which adds an intimate and personalized feel. Everyone feels well taken care of, and guides are happy to answer questions or assist with photos. Their professionalism makes a difference, especially when safety is a primary concern inside a volcano chamber.

The Food and End-of-Tour Comfort

After the descent, you’ll return to the base camp for a warm meal and drinks. Many reviewers highlight the lamb or vegetarian soup, describing it as “delicious” and “well-deserved after the hike.” Hot coffee, tea, and hot chocolate are also available, making it a cozy end to an adventure that often involves unpredictable weather.

The food isn’t just for comfort; it’s a thoughtful touch that shows the organizers care about your overall experience. It’s a good chance to relax, share stories with fellow travelers, and reflect on what you’ve just seen.

Pricing and Value

At $408 per person, this tour isn’t exactly cheap, but many reviewers say it’s worth every penny. What you’re paying for is not only the opportunity to go inside a volcano but also expert guiding, safety gear, a scenic hike, and a very rare experience. Some mention that the inside of the chamber’s colors and the views are worth the price, especially considering how few people get to see this phenomenon firsthand.

It’s also important to note that the experience is quite comprehensive — from the initial hike to the inside exploration and the warm meal afterward. For those who find the price a bit high, the value lies in the uniqueness and quality of the experience rather than just the activity itself.

Weather and Practical Tips

Iceland’s weather can be unpredictable, and many reviews mention rain, wind, and sometimes snow. Guides are prepared with raincoats and gear, but you should come prepared with good hiking shoes and warm clothes. Gaiters are recommended if rain and wind are heavy, as moisture can creep into shoes despite waterproof gear.

The tour lasts about 4-6 hours, covering transportation, hiking, inside exploration, and meal. It’s quite full, so be ready for a bit of physical activity but also plenty of breathtaking scenery and memorable moments.

Who Should Consider This Tour?

This experience is best suited for adventurous travelers who don’t mind moderate hiking and are eager to see something truly rare. If heights and uneven terrain don’t bother you, you’ll likely find the descent into the volcano both exhilarating and awe-inspiring. Due to the physical nature of the hike and descent, it’s not recommended for those with mobility impairments.

People who love learning about volcanoes or want a story to tell for years will find this especially compelling. If you’re traveling with family, keep in mind the physical requirements, but older travelers who are active and enjoy a challenge also highly praise it.
