Hengill Volcanic area in wintertime.
Hengill volcano is situated in the southwest of Iceland, to the south of Þingvellir. The volcano covers an area of about 100 km².
The volcano is still active, evidenced by its numerous hot springs and fumaroles, but the last eruption occurred approximately 2,000 years ago.
Some folk tales and sagas are connected to the region. For example, a young farmer is said to have killed the sleeping troll woman Jóra while she lay in wait for innocent wanderers or horsemen on the trail over Dyrafjöll.
