The direct route is very scenic from Geneva along the shores of the lake then entering into the Rhone Valley with mountains on bothsides of the train. At Visp you have to change into the narrow gauge train which climbs the steep Matter valley passing some pretty alpine villages to Zermatt.

The train journey from Zermatt to Geneva is exceptionally scenic, offering travelers a diverse look at the Swiss landscape. The first leg of the trip involves the descent from the car-free village of Zermatt down to Visp via the Matterhorn Gotthard Bahn, featuring steep mountain slopes and deep valleys. Once you transfer to the main Swiss Federal Railways (SBB) line heading toward Geneva, the train traverses the expansive Rhone Valley, flanked by dramatic Alpine peaks. The highlight of the journey occurs as the train approaches the Vaud region; the tracks run directly alongside the northern shore of Lake Geneva (Lac Léman). For the best views of the lake and the famous terraced vineyards of Lavaux—a UNESCO World Heritage site—passengers should aim to sit on the left-hand side of the train when traveling toward Geneva. This transition from rugged, high-altitude peaks to the serene, Mediterranean-like atmosphere of the lake makes it one of the most visually rewarding standard rail routes in Switzerland.
