The Gorges de Daluis is a 6 km (3.7 mi)-long canyon formed by the river Var in the Alpes-Maritimes department in southeastern France.
The canyon starts off at Guillaumes, running north to south, west of the Dôme de Barrot [fr], and ends at the small commune of Daluis, where the Var widens.
The 6-kilometer-long gorge[1] is cut in the red rock (sandstone colored by iron oxide, 260 million years old)[2] by the river Var.
Notable views along the gorge (a touristic high point[2] and one of a number of "long, lonely canyons" in the area)[3] include the final waterfall of the Clue d'Amen.
[5] Former copper mining operations in the Dôme are still visible from the gorge,[6][7] and unique mineral specimens have been found there.
