Rhine Route, Andermatt to Basel
http://www.veloland.ch/en/routen_detail.cfm?id=20814
68 km are unsurfaced and the grade and conditions are easy if you exclude Oberalp Pass.
The Rhine Route crosses Eastern Switzerland in a huge arc, accompanying the mighty Alpine river from its mountain source to the major Rhine port of Basel.
A true mountain pass excursion over Oberalp, the source of the Rhine, through Romansh-speaking Surselva. Impressive views into the wild Ruinaulta Gorge; Chur, the Rhaetian capital; with the Traubenkocher (warm wind) through the Bündner Herrschaft and on the Rhine dam to the wide Bodensee. Orchards, castles and cheerful tourist chatter along the shores of the green and silver shimmering «Schwabian Sea».
Peaceful, dense woodland to the thundering Rhine Falls at Schaffhausen. Mighty river tamed by 11 power stations. Along the route: romantic riverside paths, asparagus fields, timber-framed houses, pylons, salt towers, motorways, Swiss-German bridge towns, Roman ruins, agglomeration bustle and at last Basel's sweet speciality, Läckerli biscuits and freight ships in the three-country corner around Basel. by thunderthighs
