Aspen has an established sister city relationship with Chamonix, France in 1987.
Chamonix-Mont-Blanc, more commonly known simply as Chamonix (formerly also spelled Chamounix), is a commune in the Haute-Savoie département in the Rhône-Alpes region in south-eastern France. It was the site of the first Winter Olympics in 1924. The commune’s population of around 9,800 ranks 865th within the country of France.
Situated near the massive peaks of the Aiguilles Rouges and most notably the Aiguille du Midi, Chamonix is one of the oldest ski resorts in France and is known as the "gateway to the European Cascades."
