Two mountain ranges, two regions, two parks: different environments for structure and nature, both World Heritage Sites, united by the continuous line of the Alta Via n. 2, which from Feltre, through the Vette Feltrine and the Pale di San Martino, reaches the Valles Pass.
 
Alta Via n. 2 connects the Dolomiti Bellunesi National Park and the Paneveggio Pale di San Martino Natural Park, places where biodiversity manifests in all its beauty.

The great richness and rarity of the flora makes the former a botanical jewel, while the latter
exalts the geological and forestry beauties.
