Hraunfossar is a series of waterfalls formed by rivulets streaming over a distance of about 900 metres out of the Hallmundarhraun, a lava field which flowed from an eruption of one of the volcanoes lying under the glacier Langjökul. Hraun means lava and fossar mean waterfalls, so the name basically means Lava Waterfalls.The water originates from Langjökull glacier, the second-largest glacier in Iceland, therefore, making it the twin brother to the powerful Gullfoss waterfall. The glacial meltwater has to travel quite a long distance to Hallmundarhraun filtering through the lava field and spouting out again in an incredible water array.

Langjökull is the second largest ice cap in Iceland, after Vatnajökull. It is situated in the west of the Icelandic interior or Highlands of Iceland and can be seen clearly from Haukadalur. Its volume is 195 km³ and the ice is up to 580 m thick. The highest point of the ice cap is about 1,450 m above sea level. At least two volcanic systems can be found under Langjökull glacier but have been dormant for thousands of years

Húsafell is quite inland for an Icelandic settlement, made possible due to the fertile lands and relative lack of eruptions in the area. In spite of its distance from the coast, fishing has always been popular due to the trout lakes and salmon rivers within it. A rectory once stood on the farm, gaining it fame as a location across the country when it was in its deepest religious throes, although all that remains now is a church. Today, Húsafell is most popular and well-known as a camping location. There are many campsites, cabins, bungalows and holiday homes to be rented in the area, making it very popular amongst both locals and travellers. The old farmhouse, dating back to 1904, is also now a hotel.
