Visitors must begin their journey in the Blue Mountains region, not far from Reykjavik. From there, they have to hike to Thrihnukagigur, which is a 45-minute trip that takes them past volcanic fields, gas tunnels and sculpted volcanic cones. Explorers are then lowered into the volcano by a special lift. Compare Stefánsson’s first trip, which involved him descending into the volcano by rope in darkness! As you can see in these photographs, the textures and colors of the lava on the walls are quite spectacular.
