From Plainpalais to Arve
The Arve river flows for approximately 100 km (62 miles) through France , in the département of Haute-Savoie , and (for a few kilometers) in Switzerland . It is a left tributary of the Rhône . Rising in the Graian Alps , close to the Swiss border, it receives water from the many glaciers of the Chamonix valley (mainly the Mer de Glace ) before flowing north-west into the Rhône on the west side of Geneva , where its much higher level of silt brings forth a striking contrast between the two rivers. The Arve flows through Chamonix , Sallanches , Cluses , Bonneville , Annemasse and Geneva.
