This lakeside promenade is brilliant. Even non-botanists can admire great, old subtropical plants and fantastic seasonal flower arrangements here. In spring, the snowfields of the mountains on the southern shore (Haute Savoie) compete with the sparkling and glittering stars on the waves of Lake Geneva. A dream.

The bridge over the Rhône River for walkers and cyclists. The light green color of the water is due to the sediment carried by the current.

The descent from Chatel to Monthey is sensational! The other way around, however, is hell due to the traffic!
