Signal d'Uchon, Mountain summit in Saône-et-Loire, Burgundy, France

Signal d'Uchon is a granite summit in the southern reaches of Morvan with an elevation of 681 meters above sea level. The slopes are steep and demand attention and proper footwear from anyone making the ascent.

This peak was a local landmark for years but gained wider recognition in 2021 when it first appeared in the Tour de France. That inclusion marked a turning point in how the climbing community viewed this mountain.

The name Uchon comes from the Gaulish word uxello, meaning "high". The granite boulders around the summit carry fanciful names such as la Griffe du Diable (the Devil's Claw), la Pierre qui Croule, le Mammouth and le Nez de Chien, which have inspired local tales and legends.

The route to the summit has varying gradients and can be demanding, especially in poor weather or rain when the granite becomes slippery. Good footwear and plenty of water are always wise for this climb.

The boulders near the summit, known as the Rochers du Carnaval, are granite freed by erosion of their weathered crust and sandy arena. One of them, la Griffe du Diable, has deep vertical grooves that are erosion marks, not the polished grooves of a polissoir. The site has been a protected classified site since 28 July 1940.
