You now find yourself in the company of ‘Romsdal Aktiv', in a canoe on the winding and idyllic river Istra. The river which runs wild and unabated down from Trollstigen (the Troll-ladder), then changes character dramatically on its course through Isterdalen (Ister valley). The river continues on its serene path through a series of acute bends and "Troll-like" nature.
