The coolness in these gorges is much appreciated when it's close to a heatwave on the plains! And the wild atmosphere of the small road through these gorges (before reaching a busy road for a beautiful descent) is good (a little "kick in the ass" to get out!).

In 1915, a mountaineer from Montaud came to visit his family via the Pas de la Clé. When he returned the next day, he could not go further than the Gève refuge. The forest was devastated, the trees uprooted and tangled. A hurricane had almost completely destroyed the Ture sector. Until 1939, no felling was carried out, so as to allow the forest stand to regenerate.

Magnificent plateau accessible on foot from Engins, by bike from the mortar tunnel or from Les Égauds (mountain bike/gravel) or by car from Autrans. Shuttles make the bus trip to limit the number of cars.... Summer or winter, the panorama is just magnificent. Chartreuse, Belledonne and on a clear day you can see Mont Blanc perfectly.
