Pontarlier is a mountain town located 837 meters above sea level in the heart of the Jura Mountains. As the capital of Haut Doubs, it is located at the entrance to a vast area of protected natural areas, where forests, lakes and green meadows are essential for the production of Mont d'Or and Comté cheese. Pontarlier was once known worldwide for its production of absinthe at the beginning of the last century. Today, the city has revived this tradition, with two distilleries once again producing absinthe.
