Piz Lad, Mountain summit in Sesvenna Range, Switzerland and Italy

Piz Lad is a mountain summit in the Sesvenna Range located on the border between South Tyrol and the Swiss canton of Graubünden, reaching 2,808 meters high. The peak stands at the boundary line between Italy and Switzerland, dividing two distinct alpine regions.

The mountain sits near a tripoint boundary where Italy, Switzerland, and Austria meet, positioned 800 meters north of the summit. This border region held military and territorial importance across different periods of European history.

The name Piz Lad comes from the Vallader Romansh for "broad peak", referring to the mountain's wide, fairly level ridge. The summit cross stands at 2,784 m at the northeastern end of the ridge, while the highest point lies farther southwest along the same crest. Since 1919 the mountain has marked the border between Italy and Switzerland.

The easiest route starts at Reschen and leads via the Reschener Alm at 2,020 m on a marked trail; the path is drivable up to the alm, and from there the summit takes about 2½ hours. The summit cross stands at 2,784 m at the north-eastern end of the ridge, while the highest point lies further south-west along the nearly level ridge.

The tripoint where Italy, Switzerland and Austria meet lies about 750 metres north of the summit, at 2,180 metres, not on the peak itself. Until 1919 the three-state border stood further east at Cima Garibaldi (2,838 m) near the Stelvio Pass. The summit cross stands at 2,784 m on the north-eastern end of the ridge, while the highest point lies further south-west along the nearly level crest.
