Hengill volcano lies about 30 km from Reykjavik. The last eruption was about 2000 years ago but the volcano is still showing high geothermal activity. There are two power plants in this area which provide renewable energy renewable energy for Reykjavík and the surrounding villages. There are a plenty of amazing hiking trails here, all are well constructed and properly signposted. The landscape is extremely varied and beautiful. Mossy covered lava fields, volcanic rock formations, boiling hot springs and hot rivers, steam rises in every direction. Warmly recommended!
