I was fortunate enough to get the opportunity to hike up to Fimmvörðuháls with some geologists from work. They were collecting samples and measuring  temperatures near the craters Magni and Móði that were formed during the eruption in March 2010.

Crater Magni in FImmvörðuháls

The crater Magni formed in the eruption 2010 in Fimmvörðuháls.

Fimmvörðuháls is a mountain ridge located between Eyjafjallajökull glacier and Mýrdalsjökull glacier and reaching up to 1100 m. Hiking across Fimmvörðuháls between Skógar and Þórsmörk is very popular, especially during Midsummer’s Day, the longest day of the year.

The hike is quite strenuous and steep but it is worth the effort. It is very important to wear appropriate hiking boots and clothing that protects you from the cold and windy weather between the glaciers. Even though the weather is warm and sunny in Skógar or Þórsmörk it can change very rapidly on the mountain.

I had hiked Fimmvörðuháls several years before but this hike with the geologists was especially interesting. Two years after the eruption, the heat in Magni crater was over 400°C (750 F) 15 cm below the surface. Quite hot! No wonder that the crater was still steaming.

It was also very interesting to see the various colors of the lava, black, grey and red. The red color was especially beautiful.

How to get there:
Skógar is by ring road no. 1. The hike from there to Fimmvörðuháls takes about 6 hours and all the way to Þórsmörk around 9 hours. Please get current information on the track and follow the weather forecast if you plan to do the hike.
