Nestled between Martigny and the French border, the Trient Valley forms a wild Alpine corridor overlooked by the steep slopes of the Mont Blanc massif. It stretches from the Trient Glacier, perched at nearly 3,000 m above sea level, down to the edge of the Rhône plain at Vernayaz. This side valley on the left bank of the Rhône is home to several mountain villages : Salvan, Les Marécottes, Finhaut and Trient.
The valley’s geographical position makes it an accessible area that has nonetheless remained perfectly preserved. The main access point is Martigny, where regional trains, InterCity services and roads from Lake Geneva, the Upper Valais and the Simplon all converge.
From there, you can head up into the valley along the winding road towards Vernayaz, then Salvan and Les Marécottes, or aboard the Mont-Blanc Express. This century-old railway line linking Martigny to Chamonix offers one of the most iconic scenic journeys in the region, suspended above gorges and crossing viaducts and deep forests.
To the east, the valley opens towards the Mont Blanc massif via the Châtelard–Finhaut border crossing and Vallorcine. This gateway provides quick connections to Chamonix, Argentière and the Col de la Forclaz, a route much loved by cyclists and motorcyclists in the warmer months.
