Bláhnjúkur
Bláhnjúkur is a volcano in the south of Iceland. Its height is about 940 m.
Its name translates to blue peak in English. This comes from the blue-black colour of its sides. The colour is due to volcanic ash and lava flows.
The mountain is situated in Landmannalaugar, a natural park near Hekla. It lies next to the volcano Brennisteinsalda.
A hiking trail leads up to the top of the mountain from which, in good conditions, five glaciers are visible.
