Description

Aujourd’hui, la frontière franco-italienne se franchit librement. Pourtant, durant des siècles, les Alpes ont constitué à la fois un obstacle naturel et un axe majeur de passage. Pour protéger ces voies d’accès, les États ont édifié forts, casemates, blockhaus et observatoires, dont les vestiges jalonnent encore les crêtes et vallées.

The GRP® Ubaye – Pays du Viso is a long-distance hiking route linking the Ubaye Valley, in the Southern Alps, to the valleys of the Italian Piedmont around Mont Viso.

This network of trails forms several loop treks of 2 to 6 days, allowing you to discover the Chambeyron - Oronaye massif, a spectacular high mountain territory, marked by exceptional geology, preserved nature and a unique historical heritage.

Between high mountain passes, glacial lakes, wild valleys and alpine villages, each of these routes reveals a different facet of this cross-border territory.

Details concerning animals This hike takes you to the heart of the Mercantour National Park. Dogs are strictly prohibited, even on a leash or carried by a person.
