Rocca Blancia, Summit and mountain peak in Piedmont, Italy and Provence-Alpes-Côte d'Azur, France

Rocca Blancia is a 3,193 m peak on the main Alpine watershed between Italy's Valle Maira and France's Ubaye valley. Its upper half is exposed gray rock with blocky, layered faces and deep vertical fissures; below, broad fans of pale gray scree slope down its flanks, with small snow patches in the lower gullies. On the French side, dolomites of various colors crop out low down, while the summit and Italian side consist of sandy flysch of the Eyssilloun unit. A notable fault with a subhorizontal plane is clearly visible on the southwest side.

The peak lies on the main Alpine watershed between the Maira valley in Italy and the Ubaye valley in France, and its summit is the highest point of the ridge running from Monte Sautron to the Brec de Chambeyron. The Italian IGM maps label it Rocca Blancia, the French IGN maps Rocca Blanca, and some hiking maps such as the IGC 1:50,000 sheet give Roche Blanche. The normal ascent, graded R4 on the French scale, starts from Meyronnes, a hamlet of Saint-Paul-sur-Ubaye, climbs past the lower Vallonet lake and reaches the saddle between the two summits at 3,120 m.

The name appears as Rocca Blancia on Italian IGM maps and as Rocca Blanca on French IGN maps; the IGC 1:50,000 hiking map labels it Roche Blanche. The summit marks the watershed between the Maira valley and the Ubaye valley, and the normal route starts from Meyronnes, a hamlet of Saint-Paul-sur-Ubaye, where the Vallonet stream is followed up to its lower lake.

The standard route climbs the western slope from Meyronnes following marked trails that pass a lower lake before reaching steeper terrain. Good physical fitness and proper hiking boots are important, as the ascent becomes increasingly steep and the altitude requires acclimatization.

The summit and the Italian side consist of Eyssilloun sandy flysch, while coloured dolomites crop out lower on the French side. A nearly horizontal fault plane cuts the mountain and is clearly visible on the southwest face. The normal route reaches the 3,120 m saddle between the main summit and the 3,165 m secondary top before turning right to the cross.
