Sentier géologique des Monts d'Or

Ce sentier de découverte vous invite à un voyage à travers les temps géologiques, de l'époque des premiers poissons jusqu'au temps des dinosaures.


He offers a life-sized journey through the area's geological history, from the bedrock formation in the most ancient times to the Marine Jurassic age.

A 4.5-km hiking trail, from the village of Chasselay to Poleymieux-au-Mont-d'Or, takes you past three major geological structures. The crystalline basement from the Primary Period, created 500 to 360 Mya; the sedimentary series from the Secondary Period, geologically formed in the period between 240 and 160 Mya; and a network of normal faults that cut the massif in half in the Tertiary Period around 30 Mya.

The Mont d'Or massif is a whole separate entity in the Beaujolais region, with its own geological history; however, it is part of the regional geological history in that its formation was strongly influenced by the orogenesis of the Massif Central.

Geopark Beaujolais

Famous throughout the world for its wines and vineyards, the Beaujolais is also a region shaped by man, who has reaped the benefits of the soil's diversity. Its past is literally written in stone: in the golden, red, white, grey or black rocks and stones that have visibly been put to good use in local construction. This remarkable geology has given rise to great diversity, not only in the landscapes and heritage, but also in terms of human activity, in the culture and traditions that form the identity of the Beaujolais region.
