Cima Nera, Mountain summit in Trentino-Alto Adige, Italy

Cima Nera is a 3,037-metre summit in the Ortles-Cevedale group of the Rhaetian Alps, above the Val de la Mare, a side valley of the Val di Peio. With Cima Lagolungo it is the only peak of that valley lying entirely in Trentino. Its slopes hold remains of a World War I military observatory.

The mountain was part of the Alpine front during World War I and still bears marks from that period. Trenches and fortified positions remain visible along the slopes.

The summit lies in the Val de la Mare, a side valley of Val di Peio, and is one of only two peaks there lying entirely in Trentino. Walkers pass the Larcher al Cevedale refuge at 2,607 m and the Lago delle Marmotte at 2,701 m, both named in local usage. A wartime cross stands on the top.

The usual route starts at Malga Mare (2,031 m) and follows SAT trail 102 to Pian Venezia, then continues to Rifugio Larcher al Cevedale (2,607 m). From there the path heads east to Lago delle Marmotte (2,701 m), then north to the summit, about 45 minutes from the lake. The climb covers 1,006 m of ascent and is rated E; hands are needed above 3,000 m.

A wooden cross stands at the summit alongside remnants of wartime fortifications. From this vantage point, visitors can look down into three different valleys at once.
