Stage 3: St.-Gotthard-vier-Pässe-Bike

The Oberalp Pass connects the cantons of Grisons and Uri. The only lighthouse in the Alps stands here, and it is symbolic of the source of the Rhine. The descent towards Sedrun leads into Val Obecalp via Pass Tiarms. There are then three more valleys that run alternately upwards and downwards: Val Giuf, Val Mila and Val Strem.
