Check out this drone video of the famed Les Trois Vallées ski resort in the French Alps, compliments of top AirVuz contributor and pilot HendrikW. Located in the Tarentaise Valley in the Savoy Department, Les Trois Vallées was originally three different resorts until the early 1970's when they were linked together by ski lifts. With 600 km (around 375 mi.) of alpine runs, 183 lifts, and 120 km (about 70 mi.) of cross-country ski trails, it's considered the largest single ski complex in the world.
