Itinerary
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.
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.
Located just outside Reykjavík, the Bláfjöll (Blue Mountains) set the scene for your adventure. These rugged volcanic peaks are home to the Thrihnukagigur volcano and are known for their dramatic terrain and otherworldly beauty. It’s a striking backdrop for the start of your hike.
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. The tour concludes with a scenic drive back to Reykjavík.

About Reykjavik
Reykjavik is the northernmost capital of any nation, a colourful, compact city of art and music that opens onto Iceland's volcanic landscapes.
The landmark Hallgrímskirkja church, its tower inspired by basalt columns, rises above streets of brightly painted houses. Down by the harbour, the glass-fronted Harpa concert hall shimmers on the water, and the Sun Voyager sculpture faces the sea toward Mount Esja. Laugavegur, the main shopping street, is lined with design shops, cafés and bars.
