The municipality is located in the Saint-Maurice district, in the Trient Valley. It consists of the village of Salvan and several hamlets, including Les Marécottes and until 1912, Vernayaz, Miéville and Gueuroz.

The territory of the municipality includes a significant portion of the Trient valley (along with the municipality of Finhaut) and two of its important side valleys: the entire Vallon d'Emaney (drained by the Triège) and the upper section of the Vallée de Barberine (drained by the Barberine and the Eau Noire) who is notably occupied by the artificial lake of Émosson. A small part of the territory of the municipality is not drained by the river Trient: it is the Vallon de Van, drained by the Salanfe which ends directly in the Rhone.

Although the municipality does not include the highest peak of the Trient Valley, several summits over 3,000 metres lie there. The highest are Tour Sallière and Mont Ruan, both in the Vallée de Barberine.
