Langisjor is among the clearest highland lakes in the country. Its altitude is 670 meters and at its deepest, it’s 75 meters.
The lake lies southwest of Vatnajokull, between the mountains Tungnarfjoll and Fogrufjoll. The beautiful Fogrufjoll mountains (literally 'The Beautiful Mountains'), to the east of the lake, are a popular hiking place and the waters allow for trout fishing.
