Ever wondered what a volcano looks like on the inside? This unique volcano tour, takes you literally inside a dormant volcano, through the top crater and to the bottom of its magma chamber, which was once filled with steaming hot lava. Iceland is one of the few places in the world where you can enter a volcano’s magma chamber. The dormant Þríhnúkagígur volcano (yeah, good luck trying to pronounce it!) is a unique natural phenomenon.
