You reach the Lai da Nalps reservoir via a climb of around eight kilometers, which begins in Surrein, just on the other side of the valley from Sedrun. The climb begins with a steeper section and a few tight bends. After that, the road becomes more even, following the right side of the valley until finally, a few beautiful switchbacks lead up to the dam. You could cycle the two kilometers to the end of the lake on a gravel road, but after that, you're definitely not going any further on two wheels.

At the Oberalp Pass at 2,044 meters, not only is the obligatory "passport photo" waiting at the Oberalp Pass sign, but also the only lighthouse in the Alps. It comes from Rotterdam, where the original lighthouse can be found in the Maritime Museum, which once stood in Hoek van Holland, at the mouth of the Rhine into the North Sea - thus completing the circle from the source to the mouth.
