Mont Blanc 3-Day Gouter Route Expedition¶

Classic 3-day ascent of Western Europe's highest peak via the Gouter Hut with the Bosses Ridge summit day and full valley descent.

Overview¶

The Gouter Route is the most popular and safest path to the 4,808m summit of Mont Blanc, the highest peak in the Alps. This 3-day itinerary ascends from Saint-Gervais through the Tramway du Mont Blanc and the notorious Gouter Couloir to overnight at the Gouter Hut at 3,817m. Summit day crosses the Bosses Ridge at dawn for the iconic view across the Alps, followed by a full descent back to the valley. A reservation at the Gouter Hut is mandatory and must be booked months in advance.

Day 1: Saint-Gervais to Gouter Hut¶

Take the Tramway du Mont Blanc to Nid d'Aigle, then climb the Gouter Couloir — a rockfall-prone gully requiring a helmet and careful timing. The modern Gouter Hut offers meals and bunks above the clouds with sweeping views toward the summit.

Day 2: Gouter Hut to Mont Blanc Summit and Return¶

Depart the hut at 3 AM and cross the Dome du Gouter to the Bosses Ridge, a narrow snow arete leading to the summit at 4,808m. Return to the hut by mid-morning to rest before the next day's descent.

Day 3: Gouter Hut to Saint-Gervais¶

Descend the Gouter Couloir and return to Nid d'Aigle for the Tramway du Mont Blanc back to Saint-Gervais. Legs are typically fatigued; take extra care on the couloir descent.
