Early Origins and Mountaineering Milestones
The Grands Mulets Hut’s legacy began in 1786, when the first successful ascent of Mont Blanc by Jacques Balmat and Michel-Gabriel Paccard employed the “voie historique” across the Bossons Glacier. Horace-Bénédict de Saussure, a pioneering scientist, commissioned the first primitive shelter at the site in 1786—a stone grotto intended as a staging post for early climbers (Amis du Vieux Chamonix).
By 1853, the first true refuge was constructed, a modest wooden cabin assembled on the glacier, later expanded to accommodate the growing number of climbers. Over the decades, several iterations followed, with significant upgrades in 1866, 1881, and notably in 1896, when the hut was rebuilt higher and outfitted with bedrooms and modern amenities for the era. In 1908, a telephone was installed—a remarkable innovation at such altitude (Amis du Vieux Chamonix).
The Modern Hut
The current structure, designed by architect Lederlin, was inaugurated in 1960. It stands on a dramatic rocky outcrop at the junction of the Bossons Glacier’s icy streams, offering both strategic position and panoramic views for climbers and ski tourers. The hut is operated by the Club Alpin Français (FFCAM official site).
The Grands Mulets Route and Its Significance
Historical and Cultural Value
Serving as the original route to Mont Blanc’s summit, the Grands Mulets route has shaped the course of alpinism in the Alps. While the popularity of alternative routes has grown, the historical path remains a coveted adventure for those seeking solitude and an authentic mountaineering experience (Alpine Mag).
Modern Use: Ski-Mountaineering Hub
Today, the hut is primarily used during the spring ski-mountaineering season (late March to late July), when snow bridges make glacier travel more secure. The route allows for a remarkable ski descent from Mont Blanc’s summit to the valley—a dream for experienced ski-mountaineers (See Chamonix; FFCAM).
