Hengill is a cluster of mountains just outside Reykjavik, Iceland's capital and largest city. One of Hengill's most distinguishing features is an extensive, beautiful geothermal area with natural hot springs and colourful steam vents. A number of scenic mountain tracks weave their way through the mountains, where travellers can dip a toe or more in natural hotspots and feel fatigue drain from their bodies.

Earthquakes are frequent in the Hengill region because it's an area of lively tectonic and volcanic activity, although 2,000 years have now passed since the last eruption.
