We enter through the top crater and descend to the bottom of its magma chamber, which was once filled with steaming hot lava. Thrihnukagigur Volcano is the only spot on earth where it’s advisable to explore a magma chamber from the inside. The volcano has not erupted for 4.000 years and shows no signs of coming to life anytime soon, so it is safe to enter.

The volcano is located approximately 25 minutes from Reykjavik. Once we arrive, we will need to hike across a lava field in order to reach the crater the surface can be hilly and uneven. The walk is moderate and usually takes around 45-50 minutes (3km / 2miles each way).

When we have reached the crater you will be lowered 120 meters (400 feet) in an open elevator for about 6 minutes. All equipment and procedures have been tested extensively and approved by the administration of Occupational Safety and Health in Iceland.
Everyone that goes down into the crater will have a harness and required to use a helmet at all times. All guides are experienced mountain guides and cave explorers and will be with you at all times.
Groups are small, so you will have the personal attention of your experienced guides.
