The Experience in Detail

The bus ride itself is often praised for its scenic quality, giving travelers a taste of Iceland’s rugged landscape before the adventure begins. Some reviews mention that the driver can be a bit “scenic” in their thrill-seeking style, but overall, transportation is smooth and reliable.

Inside the Volcano

The highlight is of course descending into the volcano’s magma chamber. After a safety briefing and getting fitted with helmets and harnesses, you’ll board a lift that slowly takes you down into the crater. The descent takes about 10 minutes, but the views and the experience are worth every second.

Inside, you’ll find an otherworldly landscape filled with vibrant colors, and the chance to walk around and explore for roughly 30 minutes. The view of the inside of the volcano is genuinely special—reviewers describe it as ‘an unforgettable sight,’ with colors and formations that seem almost surreal. One reviewer shared, “The colors in the magma chamber took my breath away.”

Experts guide you throughout, explaining the volcanic activity, the dormant state of the volcano, and the geological significance. The small group size (4-5 people) allows for personalized attention and ample time for photos and soaking in the scenery.

Post-Descent Relaxation

After the hours of adventure, you’ll return to the base camp for a well-earned warm meal. The traditional Icelandic lamb or vegetarian soup comes highly recommended, with many travelers noting it’s both hearty and delicious—a perfect way to end the day. Hot drinks like coffee, tea, or hot chocolate are available, and reviewers mention the thoughtful gesture of the warm meal after the rain or wind.

• Group Size & Safety: Small groups ensure a more intimate experience, and safety is a priority. Reviewers praise the guides’ professionalism and friendly attitude.
• Cost & Value: At $408 per person, this tour is a premium experience, but many feel the rarity and quality of the experience justify the price. Inclusion of gear, transportation, and a meal definitely add to the overall value.
