Tignes Le Lac
The best all round family base in the area, and the clear pick.
Tignes Le Lac sits high beside its frozen lake, with gentle nursery slopes rising directly above the village and an essentially car free core that lets children move safely between the apartment, the slope and the snow front. The snow is about as reliable as anywhere in the Alps, the ski school is large and well drilled, and the lakeside setting gives families a natural, traffic free hub. Beginners progress on the gentle slopes right above town before venturing further.
It takes top spot because it combines the most reliable snow, gentle doorstep terrain and a safe, contained layout. The trade is that it is a functional high altitude village rather than a charming old town.
