 The Col is also accessible by off-road mountain paths and is the highest point both of the Alpine GR5, a long-distance trail from Lake Geneva to Nice, and of the similar Grande Traversée des Alpes.The steep descent to the south, notable for its waterfalls, enters the Vanoise National Park here.From the north the road goes up and down through short tunnels and avalanche galleries past the Lac du Chevril near Tignes.
