Located in an ancient lava field near Reykjavik, the unique Thrihnukagigur volcano is one of just a handful of places in the world where you can literally descend into the heart of a volcano and explore its gigantic magma chamber.
Following 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.
Inside the volcano tour literally takes you into the volcano, through the top crater and right to the bottom of its magma chamber where molten magma flowed during an eruption 4.000-years ago.
The Thrihnukagigur volcano is reached via an hour-long walk and entered by way of an open cable lift, a descent of 120 metres.
Inside the volcano, the ground space is equivalent to around three basketball courts, and the centre cavity could easily fit the Statue of Liberty.
