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.

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.

Awesome adventure

We flew in from Boston to see the volcano up close and personal. We are an elderly couple and Nick our guide Went well above and beyond to assure our safety with rock by rock guidance of how to descend the trail. It was an experience of a lifetime and one of the best vacation guided trips we have ever taken. Anyone traveling to Iceland to witness this eruption should definitely take this guided trip with adventures.com. Nicks’ geologic knowledge added to the experience and we had lots of time at the site to walk to to view (safely) the several fissures and the fast moving lava flows. Don’t hike solo - take this guided tour. Incredibly professional and and spectacular.

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.

If desired, you can pre-pack your lunch in advance and bring it with you. But we also have a lunch break, where we make a stop in Grindavík. There you can purchase snacks and drinks for the hike. Please note, however, that your lunch is not included in the tour.  

While you’re on a hike, you’re only surrounded by nature, and there are no dedicated restrooms. We recommend that visitors use the bathrooms available in Grindavík during our lunch break before we venture off on a hike. 

Scientists and the Department of Civil Protection and Emergency Management closely monitor the area at all times. This way, the public is informed and has all the latest updates every day. Even though the site is open for a visit, the situation can change within short notice.
