Water vapor acts as fuel for clouds, and nearby bodies of water like oceans or large lakes can provide that fuel with more consistency than distant water sources.

All-time snow makes for all-time ski trips, and while every great powder day involves a little bit of good luck, some places have more than just luck on their side. Like France’s Tarantaise Valley, home to Eleven’s Hibou and Pelerin Chalets.
The Tarentaise Valley is uniquely positioned for the kinds of winter storms that skiers and snowboarders dream of. As with all of Eleven’s properties, this location was chosen for more than just its unforgettable scenery. It was hand picked for its distinct meteorological advantages, which ensure that fresh turns are the norm, not the exception.

Why Snowfall is so Consistent in the Tarentaise Valley
What are the ingredients that lead to consistent snowfall? In order to have strong winters year after year, a location needs to be able to count on three things:
1. A Consistent Source of Water Vapor
2. A Lifting Mechanism
Moisture needs to cool down and condense to create snow. Mountain ranges accomplish this by forcing air upwards to cool (a process known as orographic lift), creating cold conditions that don’t rely on other forces like weather fronts or atmospheric instability.
3. Freezing Temperatures
Snow can’t fall at temperatures warmer than 0°C (32°F). The most reliable way to get cold temperatures is through higher elevation.
Reliable Snowfall Year After Year
With geographically optimal water sources, tall mountains, high elevations, and other unique features tailor-made for huge snow totals, the Tarentaise Valley is arguably the world’s most famous “snow trap.” It’s a place where all the perfect ingredients converge to deliver run after run of soft turns, fresh tracks, and smiling faces.
Multiple Water Sources Fuel the Storm Engine

The Tarentaise Valley benefits from two primary moisture sources: the Gulf of Genoa to the east and the Atlantic Ocean to the west. With access to both resort and backcountry terrain throughout the valley, Eleven’s guides are well-positioned to follow storms throughout the region so you’ll always ski where the snow is best.
Atlantic Storms Move Through the Region
Atlantic Storms Move Through the Region
Most of the region’s biggest storms come from the Northwest, and the Tarentaise Valley sits in a prime position to catch this moisture. As these moist Atlantic air masses hit the first high peaks of the Savoie region, they’re forced upward, cooling the moisture and dumping massive amounts of snow on the valley slopes.
Cold Air Gets Trapped in the Terentaise Valley

The Tarentaise is what meteorologists call "inner-alpine." Because it’s a deep valley surrounded by high ridges, cold air often gets trapped on the valley floor. When a new warm front arrives, the warmer, moist air slides over the top of this trapped cold air, resulting in consistent snowfall at much lower elevations than might be expected elsewhere.
Cooler Temperatures Preserve Snow in the High Alps

A huge portion of the Tarentaise Valley’s skiable terrain is above 2,000 meters (6,561 feet), meaning even wet and warm storms still produce quality snow at higher elevations, where the temperature remains well below freezing. This also helps build a massive snowpack that often lasts until May.
The Retour d'Est Brings Huge Snowfalls from the Italian Coast
The Retour d'Est Brings Huge Snowfalls from the Italian Coast
While most of the region’s snow comes from the west, a "Retour d'Est" (Return from the East) occurs when a low-pressure system sits over the Gulf of Genoa, pushing moisture back against the eastern border of the Tarentaise. When this happens, regions near Val d’Isère and Tignes are known to get up a meter of snow in a single day.
