Les Grand Montets is situated above Argentière and with over 1800 hectares, is the largest of the pisted skiing areas in the Chamonix valley.
Most of the area is above the tree line with large expanses of open terrain. The upper skiing areas are located on a glacier, accessed by a second cable car. There is a marked piste from the top but you should be very aware of the presence of crevasses if you choose to venture off-piste.
Les Grands Montets can be very cold in the mornings and its shady northwesterly aspect can mean that in January and February it barely gets any sun until mid-afternoon. Later in the season Grands Montets starts to get sunnier but it is generally the least sunny of all the Chamonix ski areas. This can, however, be an advantage as it means that snow conditions will often be well preserved until the end of the season in May.
