Grand Margès, Mountain summit in Provence-Alpes-Côte d'Azur, France.

Grand Margès is a 1,576 m summit in the Var, about 3 km southeast of Aiguines, near the border with Alpes-de-Haute-Provence. Its bare reddish-brown and grey rock crest rises above a band of low dark-green scrub, with the dry yellowish plain of the Grand Plan de Canjuers below to the south. The northern side drops as cliffs into the Verdon gorges, and the mountain runs northwest to southeast, ending near the old hamlet of La Barre.

The mountain's northern side is defined by the Verdon gorges, and the D71 road along its lower slope was built in the 1940s; it passes the Col d'Illoire at 967 m and the Vaumale spring. The summit's several points, from Grand Margès at 1,576 m down to the Illoire ridges at 1,049 m, are named in the sources. The old hamlet of La Barre stands near the Petit Plan de Canjuers at the mountain's south-eastern end.

The mountain's name comes from its two summits: Grand Margès (1,576 m) and Petit Margès (1,462 m), a knoll nearby. The cirque de Vaumale, carved between Petit Margès and the Verdon gorge, takes its name from the stream whose source flows beside the road. The D71, built in the 1940s, runs along the lower north slope past the col d'Illoire (967 m) and the source de Vaumale.

Good hiking boots and plenty of water are essential for the climb since shade is sparse along the way. The best time to visit is from May through October when weather is more stable and trails are easier to access.

The summit panorama spans from Mont Ventoux and the Baronnies to the sea and the Maures massif on a west-east axis, and from the Dévoluy and Mercantour-Argentera peaks to Mont Faron on a north-south axis. The lower Verdon gorges, the Valensole plateau and the Lachens, highest point of the Var, lie below.
