Langisjor
A narrow blue lake twenty kilometres long, held between mossed ridges and unknown to Icelanders until the 1800s.
Updated 30 August 2026
Langisjor lies in a trough between the Fogrufjoll ridges south-west of Vatnajokull, about twenty kilometres long and rarely more than two wide, and its water is a deep blue that is unusual in a country where most highland lakes are grey with glacial silt. The ridges around it are covered in moss over dark rock. It is remote enough that it went unrecorded until the nineteenth century, which is remarkable for a lake this size in an inhabited country. It was drawn into Vatnajokull National Park when the park was enlarged in 2011, ending long-running proposals to divert water from the area for hydro schemes.
What's there
- A twenty kilometre trough - narrow water between two ridges.
- Blue rather than glacial grey - unusual for a highland lake here.

Practical notes
This is a long drive on rough track for a view, with nothing to do at the end but walk. There is a hut and nothing else - no fuel, food or signal. The weather here can shut the road at short notice. Wind on the ridges is constant.
