The Romsdalen valley is long and narrow with majestic towering mountains on either side. Along the valley floor in a wild and beautiful setting runs the foaming salmon river, Rauma. At Verma the Rauma runs through a 30-40 metre deep gorge, forming Slettafossen waterfall. The waterfall is secured by fences on either side and can be crossed by a bridge. At 1,000 metres, Trollveggen is Europe's tallest vertical, overhanging rock face.
