Lungernsee
A turquoise lake beside the Brunig road whose level was dropped by tunnelling in the 1830s to win farmland.
Updated 21 October 2026
Lungernsee is the lake people photograph from the Brunig road, a long turquoise strip under wooded slopes with the village at one end and a church tower that features in most of the pictures. Its history is unusual: from 1790 to 1836 the community drove a tunnel of about 400 metres to lower the natural lake and expose farmland along the shore, a huge undertaking for a small commune. In 1921 it was dammed again for a power station, the land so hard won going back under water, and since then it has served as a reservoir and the level is managed, which means the shoreline moves through the year and the lake can look markedly different between spring and autumn. A cable car climbs from Lungern to Schonbuel and Turren above.
The landscape
- Turquoise water under wooded slopes - the standard Brunig-road view.
- A lake lowered by hand - a tunnel dug 1790-1836 to win farmland.
- A managed reservoir level - the shoreline moving through the year.
- The Turren cable car - the lift to the terrace above the village.
When to go
May to October. Half a day.
Things to know
Reservoir drawdown can leave wide muddy margins and a much smaller lake than photographs show, usually late winter and spring. The main road runs along the shore, so it is not quiet. The water is cold.
Nearby
The Brunig Pass is south; Melchsee-Frutt is over the ridge east.
