The Côte de Gargantua nature reserve, known for containing the elongated spur, the "giant's little finger" (as legend has it) is located in Gressan. The spur, born from deposits of glacial origin, has stimulated popular imagination and generated the legend which gives the name of this very particular area: the Côte would be the little finger of the giant Gargantua, a character invented by Rabelais, buried under a blanket of debris.

Cycle path that connects Morgex to La Salle within the Marais Nature Reserve. The route follows a stretch of Dora Baltea crossing its alluvial plain, where there are lakes, marshes and hygrophilous woods. It is almost 4 kilometers long and allows you to avoid the Aosta state road which can be busy at peak times.
