The volcano Brennisteinsalda (sulfur wave) is only 3 km (1.9 miles) away from Landmannalaugar. It is probably the most colorful mountain of Iceland. Powerful fumaroles surround the volcano, completing the out of the world scenario. Be careful, especially the whitish ground next to the fumaroles may be only a thin crust and one may easily break through.
Whitish spots are marking the positions of fumaroles high on the slope of Brennisteinsalda.
The largest fumarole of the whole area, approximately 30 m (100 feet) across, is located near the base of the mountain slope.
A huge number of further fumaroles are scattered in the surroundings.
