The road out of Skjolden climbs the Fortun valley in a chain of hairpins, past summer farms, and comes out at Oscarshaug with the Hurrungane lined up across the valley like the teeth of a saw. It keeps climbing onto the Sognefjell plateau to Mefjellet, the highest point of the pass, where the Fannaråk and Smørstabb glaciers are in view, and comes back down past the Åsafossen waterfall.
Three hours at its shortest. Take four, and you carry on to Krossbu for coffee and waffles made while you wait.
