The Queyras (Occitan: Cairàs) is a valley located in the FrenchHautes-Alpes, of which the geographical extent is the basin of the river Guil, a tributary of the Durance. The Queyras is one of the oldest mountain ranges of the Alps, and it was one of the last ones to be opened to public tourism towards the end of the 20th century, thus being relatively untouched by environmental destruction.
The GR58, also known as the Tour du Queyras ("The tour of Queyras" in French), is a long-distance walking route that forms a 108-km hiking loop in the Queyras.
