Iceland Thrihnukagigur Volcano Tour

5 to 6 hours

Price Breakdown:


This unique volcano tour, takes you literally inside a dormant volcano, through the top crater and to the bottom of its magma chamber where molten magma flowed during an eruption.

Reached via an hour long hike and entered by way of an open cable lift, a descent of 120 metres, the ground space inside the volcano is equivalent in size to around three basketball courts, and the cavity could easily fit the Statue of Liberty.

Following an eruption magma chambers usually collapse but in Þríhnúkagígur the lava drained out like water from a pipe leaving the volcano's plumbing system empty. The Þríhnúkagígur crater is therefore one few places in the world where you can enter a magma chamber.

This was an awesome experience. The hike was a little further than we expected, so I was glad I wore my hiking boots, especially when we went into the crater. The staff was great, I got great pictures, we had a great time.

Eine Tour die in Erinnerung und unvergessen bleibt. Schon die Wanderung durch das Lavafeld ist sehr beeindruckend und die Fahrt in den Vulkan sehr interessant. Im Vulkan selber kann man die unterschiedlichen Farben selber erleben und eine Runde durch den Vulkan laufen. Die Tour sollte man bewusst genießen und sich immer wieder in Erinnerung rufen, dass man gerade mitten in einem Vulkan ist.
