Full details

Embark on an adventure of a lifetime as you explore the depths of a dormant volcano. Journeying through its top crater and descending into the once fiery magma chamber, visitors can witness the remnants of red-hot molten lava.

Our guide to Inside the Volcano

This extraordinary experience is exclusive to Iceland, making it one of the few places in the world where you can venture inside a volcano's magma chamber.

Located in a historic lava field near Reykjavik, the extraordinary Thrihnukagigur volcano stands as a rare gem among only a few destinations in the world where you can venture deep into the core of a volcano and explore its immense magma chamber.

Typically, after a volcanic eruption, magma chambers collapse. However, in the case of Thrihnukagigur, the lava drained away, leaving behind an empty plumbing system within the volcano. This unique characteristic allows visitors to enter the volcano and discover its remarkable magma chamber.

Embarking on an inside-the-volcano tour is an awe-inspiring experience that takes you right into the heart of the volcano. From the top crater to the very bottom of the magma chamber, you will witness the remnants of molten magma that once flowed during an eruption approximately 4,000 years ago.

To reach the Thrihnukagigur volcano, you'll embark on an hour-long walk through captivating surroundings. Once you arrive, you'll descend 120 meters into the volcano's depths using an open cable lift.

Once inside, you'll be astounded by the vastness of the space. The ground area within the volcano is equivalent to approximately three basketball courts, while the central cavity is large enough to easily accommodate the Statue of Liberty.

Prepare yourself for a once-in-a-lifetime adventure as you step into Thrihnukagigur volcano and witness the awe-inspiring beauty of its majestic magma chamber.
