Tour Itinerary

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.

not a happy experience with Gray Line Iceland


Though I booked 8 tickets just hours before the departure time which was definitely not wise, the slow communication made me a lot of trouble. I was noticed by email that the booking failed and 2 hours later told me that the reservation however was not cancelled and the staff would rearrange it. I tried to contact the staff via the number provided in the email, but never had the phonecall was never answered no matter what time or how many times I called. My 8 group members already arrived at the departure point and the on-site staff from another compay already helped make the rearrangement, then I received the email that Gray Line Iceland will rearrange the tour and "perfectly" ignored the my request for a valid phone number.
