Activity itinerary

Thrihnukagigur Volcano

From the base of Bláfjöll, embark on a 2-mile (3 km) guided hike across ancient lava fields. The trail is uneven and winds through a surreal volcanic landscape filled with cones and fissures. It’s a moderate hike that offers an up-close look at Iceland’s geological past. At the edge of the crater, you'll gear up with a helmet and harness before boarding an open cable elevator. This one-of-a-kind lift lowers you into the dormant volcano’s magma chamber — a rare opportunity not found anywhere else in the world. Safety briefings and professional guidance ensure a secure and memorable descent.

Reykjavik (Pass by)

The tour begins with a scenic drive from Reykjavík toward the Bláfjöll (Blue Mountains). Along the way, your guide provides fascinating insight into the geology and history of the Thrihnukagigur volcano.

Inside The Volcano

  • 5h

Descend 400 feet (120 meters) into the vast and colorful magma chamber of Thrihnukagigur. Explore this incredible natural space where the glowing lava once flowed, now solidified into a kaleidoscope of mineral-stained rock formations. Your guide will explain the volcano's last eruption and the formation of this geological wonder. After your time inside the volcano, ascend back to the surface and retrace your steps across the lava fields. Take in the final views of this unique terrain before returning to your vehicle.
