The ASTERIX comic series by the author duo Goscinny & Uderzo, which has enjoyed success far beyond France's borders, has introduced its international audience to the unexpected characters that appear here. The distinctive style with which the various inhabitants of the famous Gallic village are drawn makes each character unique.

From here begins the forbidden route to the Col de la Charmette, but aside from the somewhat technical tunnels, if you dare to defy the ban, this abandoned road offers a magnificent and entirely passable route! A timeless passage, a jewel of the Chartreuse.

The approach from the south is very nice, the descent to the north via the forest road is not allowed, but with great caution and pushing in tunnels possible
