Two altitudes with two environments: the Lognan pastures at 1 970 m and the Argentière glacier’s seracs at the 3 275 m summit. A whole universe to discover… From the Aiguille des Grands Montets: the view of the Mer de Glace, the Aiguille de Chamonix, the Mont-Blanc and the Chamonix valley. From the Point de Vue (1 hr00 walk from Lognan): the scenery of one of the most spectacular ice falls of the valley and the departure of mountaineers for the Aiguille Verte and the summits of the massif.
