Inside a Volcano | Þríhnúkagígur - South

Ever wanted to know 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, once filled with steaming hot lava. Þríhnúkagígur Volcano is the only place on earth where it is safe to explore a magma chamber on the inside. The volcano has not erupted for 4,000 years and shows no signs of coming to life again anytime soon. Hence, you are safe! Daily from 15 May to 15 October.
