Description
From the Città di Chivasso hut cross the plateau, branching past the Rosset and Leità lakes to the Col Rosset (3,023 m), a viewpoint over the Granta Parey, “queen” of the Rhêmes valley. The long descent through the Vaudala valley returns to the Aosta Valley at Rhêmes-Notre-Dame (1,725 m).
A big-mountain stage on the Park’s Piedmont side. From the hut you skirt Lake Rosset, leave the pyramid of the Granta Parey — the “Matterhorn of the Rhêmes valley” — to your right, and ascend the stony valley to the Col Rosset, a often windy notch at 3,023 metres. The descent through the Vaudala valley is long and lonely: scree, then pastures, finally the woods above Rhêmes-Notre-Dame, the smallest municipality in the Aosta Valley, where the Park visitor centre tells the story of the bearded vulture’s return. Water only at the high lakes: leave with full bottles.

Earth sciences
Geology & landscape
Gran Paradiso, like Monte Rosa, is an internal crystalline massif of the Penninic nappes: augen orthogneisses derived from Permian granites, wrapped in a sheath of calcschists with greenstones — metamorphosed ocean floor the tour crosses at the Lauson, Rosset and Entrelor passes. At the Nivolet the plateaus are carved in the softer calcschists, while the Valnontey walls expose the massif’s gneissic core.
History & culture
Ceresole Reale received its “Royal” title from Vittorio Emanuele II in 1862: the Orco valley was the Piedmont side of the royal hunts, linked to Valsavarenche by the Nivolet mule tracks.
Water sources
Water at the stage's support points (Rifugio Città di Chivasso, Rhêmes-Notre-Dame). On the high ground and at the passes springs are not guaranteed: fill bottles in the valley and at the huts.
Getting there
Cross-border stage: on the foreign sides local public transport applies (PostAuto in Switzerland, line buses in France/Piedmont). Check seasonal timetables; in peak season several access links run by reservation only.
Warnings
- Check the weather: long high-altitude stages with few escape routes
- Snowfields possible on the passes until early July
- Book overnight stops in peak season
