What is the longest run in the three valleys?

The longest run in the Three Valleys ski area, which is the largest linked ski area in the world, is the "Vallée Blanche." This impressive descent spans approximately 23 kilometers (around 14 miles) and takes skiers from the top of the Cime de la Caron down to the village of Les Menuires. The run offers stunning scenery and a mix of terrain, making it a favorite among experienced skiers. However, it's important to note that it is not always groomed, so skiers should be prepared for varying conditions.
