Monte Roisetta, Alpine summit in Aosta Valley, Italy

Monte Roisetta is an Alpine summit in the Pennine Alps with two distinct peaks connected by a ridge. The southern peak stands lower in elevation but remains more accessible for mountaineers than its northern counterpart.

The sources record no first ascent date for Monte Roisetta. The mountain's name derives from the same Latin root as Monte Rosa, rosia, via the Valdostan patois words rouése or rouja, meaning glacier. Its two summits, the south at 3,324 m and the north at 3,334 m, are joined by a ridge.

The name Roisettaz shares its root with Monte Rosa, from the Latin rosia via the Valdostan patois rouése or rouja, meaning glacier. In patois pronunciation the final z is dropped, giving "Ruasètta"; the z was a scribal mark added in Piedmont-Sardinia registers to show stress on the penultimate syllable, and is often wrongly sounded by Italian and French speakers alike.

The usual ascent starts from the parking area about 100 m below Cheneil, which has no public road. From Cheneil, marked trails lead to Alp Ledzan (2684 m) either directly along the stream or via a gentler arc toward Col de Nana; allow about four hours to the south summit. The north summit is reached over a brittle ridge that is hazardous when wet or snowy.

The name Roisettaz shares its root with Monte Rosa, from the Latin rosia via the Valdostan patois rouése or rouja, meaning glacier. The final z is silent, so it is pronounced "Ruasètta", not as in standard French.
