Trolltunga in 3D

The Troll's Tongue · 700 m above the lake

Above Ringedalsvatnet, near Odda, Vestland, Norway

Trolltunga, the Troll's Tongue, is a slab of bedrock about 10 m long sticking straight out over a 700 m drop to the lake Ringedalsvatnet. Geologists think water froze in joints along the cliff edge as the last ice sheet retreated, prising away the rock around it. This walk lets you step out onto it.

The tongue: About 10 m of rock jutting over the drop
Height: About 1,100 m above sea level, 700 m above the lake
