Skyward Over Ice: Seeing Bossons Glacier from a Tandem Paraglide
Soar above Bossons Glacier and see Mont Blanc like a map
There’s a moment in Chamonix when the world organizes itself around a single line: Mont Blanc’s serrated ridge, the silver braid of the Bossons Glacier descending from it, and the valley that gathers both like a pair of cupped hands. Stand on the lip above Les Bossons at dawn and you can watch sunlight edge the icefall in a bluish sheen that seems almost deliberate—as if the glacier is holding its breath for the day. From that vantage the glacier feels enormous and stubborn, a river of ice still pushing through the long, weathered bones of the Mont Blanc massif.
Trail Wisdom
Book a morning slot
Morning flights often have calmer winds and clearer visibility; reserve early to avoid afternoon thermals that can make landings bumpier.
Layer for altitude
Temperatures at launch are significantly cooler—bring an insulated shell even on warm valley days.
Listen to the pilot
Follow takeoff and landing instructions closely; most tandem launches require only a short run but timing is key for a smooth touchdown.
Combine air and ground views
Pair the flight with a short hike to the glacier terminus at Les Bossons to compare aerial patterns with on-the-ground glacial features.

Conservation Note
Local research teams monitor Bossons’ retreat; visitors are asked to stay on marked paths and avoid removing ice or rocks to reduce local impact.
During the Little Ice Age the Bossons Glacier extended much further down the valley; 19th-century drawings show it reaching nearer to valley settlements.
Seasonal Guide
spring
Best for: Snow-dusted panoramas, Quieter valley, Early-season thermals for experienced flyers
Challenges: Unstable weather, Snow on access trails
Spring offers dramatic contrast—snow on the high ridges and open valleys—though weather can be changeable and some lower trails may be snowy.
summer
Best for: Stable thermals for longer flights, Best visibility, Accessible glacier viewpoints
Challenges: Busy season, Afternoon storms in convective weather
Late summer is the most dependable time for tandem flights and glacier access: warm valley days, clearer lines of sight, and consolidated services.
fall
Best for: Crisp light and quieter trails, Golden alpine color, Stable weather windows
Challenges: Shortening daylight, Colder launch sites
Early fall is ideal for clear, crisp air and fewer crowds; plan flights earlier in the day as temperatures drop quickly.
winter
Best for: Snow-covered panorama, Seasonal paragliding for the experienced, Photographic contrast
Challenges: Cold, strong winds at launch, Reduced flight availability
Winter flights can be spectacular with a snowbound Mont Blanc, but operators run fewer trips and weather cancellations are frequent.
Photographer's Notes
What to Bring
Insulated windproof jacketEssential
Keeps you warm at 2,000m launch elevations where wind can chill quickly.
Sturdy hiking shoesEssential
Useful for approach to viewpoints and for secure footing during launch and landing.
Sunglasses with UV protectionEssential
Reduces glare off snow and ice and improves visibility from the air.
Compact camera or phone with wrist strap
Capture aerial vistas—strap it to avoid losing it during takeoff and landing.
Common Questions
How long is a typical tandem paragliding flight in Chamonix?
Most tandem flights last between 15 and 40 minutes depending on wind conditions, thermals, and the flight path chosen by the pilot.
Is paragliding over Bossons Glacier safe?
Tandem paragliding with licensed, experienced pilots is generally safe; operators will cancel flights when winds or visibility are unsafe—follow pilot instructions and safety briefings.
Can I see Bossons Glacier from the ground?
Yes—short hikes from Les Bossons lead to viewpoints near the glacier terminus; these give great context before or after a flight.
What should I wear for a flight?
Layers, an insulated windproof jacket, long pants, and sturdy shoes; temperatures at launch are cooler than in the valley and wind can be brisk.
Are flights available year-round?
Many operators offer flights year-round weather permitting, but availability and comfort vary by season—late summer and early fall offer the most stable conditions.
Do I need prior experience to do a tandem flight?
No experience is required; a brief run at takeoff and following pilot instructions are the main physical demands.
What to Pack
Insulated shell for launch; sturdy hiking shoes for viewpoints; sunglasses and sunscreen for high-albedo glare; small daypack for water and layers
Did You Know
Bossons Glacier has retreated substantially since the 19th century; historical records and maps show it extended much further into the Chamonix valley during the Little Ice Age.
Quick Travel Tips
Book tandem flights in advance; plan flights in the morning for calmer winds; carry cash for small mountain cafés; check local weather and transport (buses/taxis) for launch access
Local Flavor
Taste Savoyard cuisine in Chamonix—cheese-forward dishes like fondue and raclette—then linger over a café where locals swap route beta and weather reports; small mountain huts serve tartiflette and comfort after a brisk hike.
Logistics Snapshot
Where to go: Chamonix/Les Bossons. Booking: Reserve tandem flights ahead; confirm pickup details. Cost: Varies by operator; expect mid-range pricing for a 20–30 minute tandem. Safety: Flights are weather-dependent—arrive flexible.
Sustainability Note
Choose operators who follow local noise and flight regulations, stay on trails to protect alpine vegetation, and support glacier monitoring by visiting local science centers or donating to research initiatives.
