Rocca La Marchisa, Mountain summit in the Cottian Alps, Piedmont, Italy

Rocca La Marchisa is a 3,072 m summit on the watershed between the Varaita and Maira valleys, at the meeting point of the municipalities of Bellino, Acceglio and Prazzo. Its top is bifid, with a southern point at 3,071 m and a northern point at 3,072 m, built of quartzose and sericitic schists with outcrops of conglomeratic quartzites (Alpine Verrucano) on its flanks. Three main ridges leave the summit, towards the Colle di Vers, the Varaita valley and the Colle della Marchisa.

The summit is formed of quartzose and sericitic schists, with outcrops of conglomeratic quartzites (Alpine Verrucano) on its flanks, both dating to the Permo-Carboniferous. Its two tops, a southern one at 3,071 m and a northern one at 3,072 m, meet at the border of Bellino, Acceglio and Prazzo. The normal route climbs from the Colle di Vers over scree and easy rock steps, rated EE, and the Colle di Vers is reached from Sant'Anna di Bellino in the Varaita valley or by trail T9 from Acceglio in the Maira valley.

The mountain stands where the territories of Bellino, Acceglio and Prazzo meet, and its two crests carry the names of the passes used by shepherds and walkers between the Varaita and Maira valleys: the Colle di Vers, the Colle della Marchisa and the Colle delle Sagneres. The normal route from the Colle di Vers is graded EE, and the winter ski-mountaineering lines climb the Traversagn valley from Sant'Anna di Bellino.

The summit is best reached in summer when snow has melted and mountain trails are clearly visible. The approach requires basic mountaineering skills and proper equipment for Alpine terrain.

This peak ranks as the 64th highest among 1,646 mountains in Cuneo province and maintains an isolation distance of 6.99 kilometers from neighboring summits.
