Peaks close in on the valley from both sides: the Aiguille du Midi rises to 3,842 m, its cable car landing on a terrace that looks straight across at Mont Blanc, 4,808 m. The Montenvers railway climbs to the Mer de Glace, where ice caves are cut fresh each season. Below, waterfalls, high meadows and timber chalets keep Chamonix in human scale.
