The volcano is an important source of energy for the south of the country, which is captured at the Nesjavellir power station (near the western shore of the lake Þingvallavatn) and the Hellisheiði power station (approximately 11 km southwest of Nesjavellir). Both stations are operated by Orkuveita Reykjavíkur (Reykjavik Energy).
The area with its mountains and hot springs is well suited for hiking and there are a lot of hiking trails. The small town of Hveragerði with its multitude of hot springs is also part of the Hengill area.
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.
