Crêt de l'Aigle, Mountain summit in Leschaux, France.

Crêt de l'Aigle is a hogback summit of 1,584 metres on the ridge above Leschaux and Gruffy, about 14 km north of Annecy. Its slopes fall away as wooded hillsides to the west and as steeper mountain terrain to the south, and the summit opens onto the Bornes, Aravis and Mont Blanc ranges.

Shepherds have long used the slopes as summer pastures for their flocks during mountain migrations. This long-standing practice shaped the cultural landscape of the region over time.

The summit's name, Crêt de l'Aigle (Eagle's Crest), refers to the ridge's shape and the birds once seen there. Local herders still bring flocks to the high pastures in summer, keeping a tradition alive.

The summit sits at 1,584 m, about 13.7 km north of Annecy, on the border of Leschaux and Gruffy. The climb gains real height, so plan several hours and carry water; the ground is forested on the approach. Sturdy footwear helps on the steeper sections.

The summit lies on the boundary between Leschaux and Gruffy, 13.7 km north of Annecy, and reaches 1,584 metres according to the source, with a nearby point at 1,660 metres about 1.1 km to the south. The slopes below are wooded, and the surrounding area is sparsely populated, with about 27 inhabitants per square kilometre.
