Iceland is one of the few places in the world where you can enter a volcano's magma chamber, and this adventure takes you to the inside of the dormant volcano Thrihnukagigur. Enter through the top crater via an open cable lift and descend to the bottom of its magma chamber that once was filled with red-hot molten lava. Located in an ancient lava field near Reykjavik, the unique Thrihnukagigur volcano is one of the few places in the world where you can explore the gigantic magma chamber from the inside. After a volcanic eruption, magma chambers usually collapse, but in Thrihnukagigur, the lava drained out like water from a pipe leaving the volcano's plumbing system empty. For this reason, Thrihnukagigur crater is one of few places in the world where you can enter a volcano and explore its magma chamber. The volcano is reached via an hour-long walk and entered via an open cable lift, a descent of 120 meters. The volcano's ground space is equivalent to around three basketball courts, and the center cavity could easily fit the Statue of Liberty.
