When Eyjafjallajökull erupted in 2010, the world stopped. Or much of Europe’s air traffic, at any rate. Locally, it forced the evacuation 800 people, and nearby farms were covered under a thick layer of ash. You wouldn’t know that when you drive past today, but there is a very interesting information centre just off the Ring Road – have a look at the 20 min video, narrated by one of the farmers. It is possible to hike up to the Eyjafjallajökull glacier and volcano, but it is a steep, full-day hike, and best not attempted without a guide. For those who don’t quite feel up to that challenge, and cannot afford to see it from the air, stop by the photographic sign in front of the farm – this will at least give you a good idea of what it looked like during the eruption.
