It originates at an elevation of 2,400 metres where it is fed by the confluence of Glacier du Géant, Glacier de Lechaud and Cascade du Talèfre, north of Mont Tacul, and descends to 1,400 metres. It flows north-north-west between Aiguille du Moine on the east and Trélaporte on the west. Le Grand Dru lies to the north east. It was once easily visible from Chamonix, but has been shrinking and is now barely visible from below.

The Grotte de la Mer de Glace enables you to take a look at a glacier from the inside. Take warm clothes with the temperatures at -2 to -5°c.
