Start high above Chamonix at the summit of the Aiguille du Midi and descend the legendary Vallée Blanche — nearly 2,000 meters of glacier skiing through the heart of the Mont Blanc Massif. Guided by Jason Antin, IFMGA/UIAGM, the day emphasizes smart route choice, glacier awareness, and smooth pacing so you can ski confidently and take it all in. Ideal for strong intermediate to advanced off-piste skiers. When conditions allow, we’ll ski to Chamonix; otherwise, we finish via the scenic Montenvers train. If needed, we’ll pivot to another excellent objective in the valley to ensure a safe, rewarding day.

Meeting Time: 8:00 AM Meeting Location: Aiguille du Midi lift station, Chamonix Estimated Return: Approximately 1:00 PM (conditions dependent) The Plan We begin with an early ascent to the summit of the Aiguille du Midi (3,842m). After a gear check and safety briefing, we descend the arête and enter the Vallée Blanche glacier system. From there, we enjoy a flowing glacier descent through the Mont Blanc Massif, managing terrain, pace, and route selection based on conditions and group ability. Finish Options • Ski toward Chamonix when snow coverage allows • Montenvers train via the Mer de Glace (standard finish on many days) • Optional quick hut stop at the Requin Hut for a coffee or snack if timing and conditions permit If the Aiguille du Midi is closed or mountain hazards require adjustment, we will pivot to an alternative high-quality objective elsewhere in the Chamonix valley. What We’ll Cover Pre-Descent Briefing • Equipment check & avalanche safety review • Glacier travel overview • Route plan and key decision points On the Glacier • Crevasse awareness and terrain management • Route selection and hazard assessment • Snow condition evaluation • Group spacing and communication • Efficient movement in glaciated terrain Ski Coaching Elements • Off-piste technique in variable snow • Managing sustained descents • Strategic regrouping and pacing
