Le col d'Ornon (n°13)

Credit : Ornon

This fairly easy itinerary through the beautiful Lignarre valley is very popular among cyclists at the beginning of the season. The last few kilometres before you reach the pass are a little more strenuous than the rest of the itinerary, but are never too exhausting. This route is nice on a summer morning when the shade of the mountains keeps it fresh.

Cultural informations : L’Oisans and its 6 valleys: the Lignarre valley
This is one of the six valleys of l’Oisans. Its name comes from the Latin word ’lignum’ (wood). Even today, it still has lots of trees and you can find some very rare plant and animal species here, such as forest orchids and the lynx. This is a small corner of the mountains of "outstanding natural beauty"! This vast remote valley beneath the ridges of the Taillefer mountains once was the gateway to the South, so that products from Southern France, such as lavender, olive oil and wine were carried over the Col d’Ornon at 1367 m. People’s livelihoods consisted of cattle-breeding, silver mining and, until the 1970s, slate mining. The great transhumance would also cross this mountain pass until the 1960s, completing the journey from l’Oisans to Salon-de-Provence in 12 days.
