Arnoga is situated at the foot of Pass da Val Viola, or in other words: it is uphill right from the start. A small asphalt road runs up Val Viola, then changes to a gravel road and finally the last section is a cart path from World War I.

The effort is well worth it: The descending road is made especially for mountain bikers and meanders through the rough mountain area down to Lagh da Viola. So this is where one of the most beautiful lakes of Switzerland is supposed to be. Lagh da Viola very well might be: surrounded by rugged mountains reflected on the smooth surface, a small islet full of larch trees. The scenery is definitely gorgeous. The route continues to a cluster of buildings, past Lagh da Saoseo. A side trip to the mountain lake is mandatory, because this is the lake that is called the most beautiful in Switzerland. If anything, it is even more charming than Lagh da Viola further up, the water is green and it nestles perfectly into the wooded landscape.

The path finally leads downhill in the direction of Poschiavo with excellent single trail sections, even if it does include two ascents, each of about 150 meters. On the bright side, the downhill ride ends directly in the middle of Poschiavo. And after the most beautiful lake in Switzerland, the centre of Poschiavo could easily be one of the most attractive in Switzerland.
