The Chartreuse Mountains is a mountain range in southeastern France, stretching from the city of Grenoble in the south to the Lac du Bourget in the north. It is part of the French Prealps, which continue as the Bauges to the north and the Vercors to the south.
One of the larger cities in the Chartreuse Mountains is Voiron.
The monastic Carthusian Order takes its name from these mountains, where its first hermitage was founded in 1084. Also derived from the mountain range's name is that of the alcoholic cordial Chartreuse produced by the monks since the 1740s, and of the chartreuse colour, named after the drink.
