The alpine stage begins around 2,000 metres (6,562 ft) with rough boulders, above which a series of broken needles spring from the Col des Montets to Le Brévent.
The Aiguilles Rouges offer a splendid view of all the peaks of Chamonix, the glaciers of Mont Blanc, and the roof of Europe.
The highest point in this range is named Belvédère (literally "beautiful viewpoint" in French) because it offers a 360° panoramic view of all the mountains surrounding the Aiguilles Rouges.
The eastern part of the range has numerous mountain lakes, of which the most remarkable is Lac Blanc at the foot of the Aiguille Belvédère.
The range is home to the principal climbing crags of Chamonix, which ascend the pinnacles of Planpraz made famous by the mountaineer Gaston Rébuffat.
