Hraunfossar

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.

Langjokull Glacier

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
