Located on the western slope of the Aravis mountain range not far from Mont Blanc, Annecy Lake and Switzerland, Le Grand-Bornand is a summer and winter resort which developed around an old village. Le Grand-Bornand is in a wide part of the valley which has allowed it to develop - the village of Petit-Bornand, located downstream, is in a narrower part of the valley. The commune of Le Grand-Bornand is made-up of three areas: the Bouchet valley, the Chinaillon valley and the village of Le Grand-Bornand located at the junction of the two valleys. The hamlet of Chinaillon to the north east of Le Grand-Bornand is the main ski centre. The valley of Bouchet is located upstream of the village along the course of the river Borne.
