Charmant Som is a mountain in the French department of Isère, rising to 1,867 metres (6,125 ft) in the Chartreuse Mountains in the Alps. It is made up of limestone, but its relief is less pronounced than that of the surrounding mountains, which is why it is covered with alpine meadows, the origin of its name. These have been occupied and tended by shepherds since the Middle Ages. They are accessible via a road built between the two world wars from the Col de Porte to 200 metres (660 ft) below the main summit. The road leads to two buildings serving as inn, chalet and cheese dairy. The mountain is part of the Chartreuse Regional Nature Park, a Natural area of ecological, faunal and floristic interest (ZNIEFF by its acronym in French) and a Natura 2000 zone. These protected areas are designed to preserve biodiversity. However, they are also ideal for hiking, speleology (which began to develop in the 1960s, followed by skiing in the late 1970s), cycling, climbing and paragliding.

The Dauphiné (UK: , US: French: [dofi'ne]) is a former province in southeastern France, whose area roughly corresponded to that of the present departments of Isère, Drôme and Hautes-Alpes. The Dauphiné was originally the Dauphiné of Viennois. In the 12th century, the local ruler Count Guigues IV of Albon (c. 1095–1142) bore a dolphin on his coat of arms and was nicknamed le Dauphin (French for 'dolphin'). His descendants changed their title from Count of Albon to Dauphin of Viennois. The state took the name of Dauphiné. It became a state of the Holy Roman Empire in the 11th century. In 1349, the Dauphiné was transferred from the last non-royal Dauphin (who had great debts and no direct heir) to the future king of France, Charles V, through the purchase of lands. The terms of the transfer stipulated that the heir apparent of France would henceforth be called le Dauphin and included significant autonomy and tax exemption for the Dauphiné region, most of which it retained only until 1457, though it remained a province until the French Revolution. Dauphin of France remained the title of the eldest son of a king of France and the heir apparent to the French crown until 1830. The historical capital is Grenoble and the other main towns are Vienne, Valence, Montélimar, Gap and Romans-sur-Isère. The demonym for its inhabitants is Dauphinois.
