Grands Montets / Normal Route via the Whymper Couloir
This is the commonly referenced normal line to the summit in many guidebook descriptions, using the Whymper Couloir from the Argentière side. It is a serious high-mountain route rather than a hike, with steep snow and ice and significant avalanche and rockfall exposure. The route is highly condition-dependent and is usually attempted when the couloir is well frozen. It requires glacier travel, cramponing, and secure movement on steep terrain. The upper mountain can be affected by spindrift and unstable snow.
