Kerlingarfjöll is a popular hiking area located in Icelandic highlands, in the middle of the country. Volcanic activity hasn't faded away completely and is still felt through geothermal activity. Hveradalir or The valley of hot springs is a magical place: the pillars of smoke rise right from rusty-red mountains painted here and there with neon-greed moss and crystal blue glacial rivers. As you hike up, and such a picture reveals below, you may feel as if you've entered some other world. Photographers come here for their best shots. However, pictures will never embrace what you can feel being there yourself and watching the beauty with your eyes.
The Hveradalir area is accessible only in the summertime, from late June to mid- or late September. Although snow melts revealing the trails with fascinating landscapes around, some stretches might be still covered in snow. Moreover, hiking conditions may also vary—don't be surprised if you spot a small avalanche on the mountainside. Also, there could be crevasses in the Fannborg Glacier.
Regardless of being an area of geothermal activity, Kerlingarfjöll once used to be a popular summer skiing destination. Since 2000 local ski school has been closed due to the temperature rise—there's too little snow to enjoy winter sports. All the same, two mountains (Fannborg and Snækollur) are still suitable for skiing enthusiasts. But you'll have to do a demanding hike for the sake of a ride (there are no facilities).
