Excellent little 2-hour ride close to home that I do regularly. Lots of twisties. Great when there is not much traffic - avoid morning & evening rush hours. Road surface is better in Switzerland than in France, but police is more of a concern in Switzerland. The descent into St. Claude is along the side of a cliff; that plus the first 10 km of the St. Cergue - Nyon bit are awesome fun.
