Volcanic eruptions are unpredictable natural events. Whether small or large fissure cracks open, they occur due to lava bursting out as well as other pyroclastic effects. Every eruption brings a rare and once-in-a-lifetime opportunity to observe the sheer power behind the lava explosion.

Not all volcanic eruptions are alike, however. Sometimes they take a slow pace when magma and gases are steadily released from the earth crust. Other times, the gases remain trapped beneath cooled magma, so they build up pressure and result in explosive eruptions that can be potentially destructive, with steaming hot ashes and boulders flying in all directions.

Thousands of earthquakes took place in the weeks before the eruption, after which the lava finally found its way and cracked through the surface of the earth. The eruption occurred on the evening of March 19th 2021, close to Mount Fagradalsfjall, in a valley named Geldingadalir. Fortunately, the valley confined the eruptive event preventing the lava from flowing towards civilian infrastructure.

The closest inhabited settlement to the site is Grindavík village, located only 9 kilometers away. Geldingadalir valley is not a secluded valley by any measures with such a short distance from a populated area. Yet, this presents a convenient way to access the eruption site for people who are willing to hike a pretty challenging terrain but for the chance to witness this magnificent spectacle of nature.

A tour like this, where you get to experience a live volcano, is one for the books! You get to observe new land formation, streams of lava flow from a fissure and right into the valley. You will witness steam and gases rise from the increasing lava field as well as the newly-appeared crater.

On this tour, you will also get to visit the Reykjanesviti Lighthouse, which is the oldest lighthouse of its kind in Iceland, followed by a stop at Gunnuhver geothermal area and the Bridge Between Continents.
