Chamonix is situated near the massive peaks of the Aiguilles Rouges and most notably the Aiguille du Midi. It isis one of the oldest ski resorts in France. The north side of the summit of Mont Blanc, and therefore the summit itself are part of the village of Chamonix. To the south side, the situation is different depending on the country. Italy considers that the border passes through the top. France considers that the boundary runs along the rocky Tournette under the summit cap, placing it entirely in French territory. The south side was in France, assigned to the commune of Saint-Gervais-les-Bains sharing the summit with its neighbour Chamonix.
The Chamonix commune is popular with skiers and mountain enthusiasts. It is possible via the cable car lift to the Aiguille du Midi to access the off-piste (backcountry) ski run of the Vallée Blanche. Chamonix is the fourth largest commune in area in mainland France.0
