Hochgebirge
The border runs along the centre of Lake Geneva, but makes landfall before reaching the mouth of the Rhône, at Saint-Gingolph, which marks the western end of the Saint-Gingolph–Saint-Maurice railway in Switzerland. A project exists to reuse a now-abandoned line to Évian-les-Bains in France and thereby reconnect the two countries by train on the south shore of Lake Geneva. From here, the border runs south and southeast into the High Alps, forming the western border of the Valais. It passes Les Cornettes de Bise (2,431 m), the Dent de Barme (2,759 m), Petit Ruan (2,846 m), the Pointe des Rosses (2,965 m), the Pointe de la Fenive (2,838 m) and Le Cheval Blanc (2,830 m), placing the Lac du Vieux Émosson in Switzerland. From Grand Perrond (2,672 m), the border descends to 1,130 m, crossing the road from Martigny to Chamonix, before ascending to Les Grandes Otanes (2,656 m), the Aiguille du Tour (3,541 m), the Aiguille d'Argentière (3,898 m), Tour Noir (3,837 m) and finally to the tripoint with the French–Italian and Swiss–Italian borders, at a point just west of Mont Dolent, and at altitude.
