Inside the Volcano

AH131 Inside the Volcano 


  • Exploring the inside of a volcano
  • Amazing colours in hues of red, yellow and purple
  • 120 metres (400 feet) descend in an open elevator

Tour Description:

This unique volcano tour literally takes you 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.

Please note: 
  • Wear proper walking/hiking shoes - about 2.5 km each way
  • Wear warm clothes - trainers and jeans is not sufficient
