Rifugio Antonio Locatelli-S. Innerkofler Italy

The Tre Cime di Lavaredo (Drei Zinnen) rise up at the southern edge of the expansive crenellated plateau with the Langen Alm (La Grava Longa), an alpine plateau at about 2200 m to 2400 m, which forms the end of the Rienz valley (Valle della Rienza). There are three small mountain lakes, the Zinnensee. This area north of the mountains up to their peaks belongs to the municipality of Dobbiaco in South Tyrol and to the Drei Zinnen Nature Park (until 2010 Natural Park Sesto Dolomites), which has been part of the UNESCO World Heritage Site since 2009.

The crest of the Tre Cime di Lavaredo, running in a west-east direction, forms the border to the municipality of Auronzo di Cadore in the province of Belluno, which is also the German-Italian language border. To the northeast, this ridge continues to the 2454 m high Paternsattel (Forcella Lavaredo), where it turns to the north to the mountains Passportenkopf (Croda di Passaporto, 2719 m) and Paternkofel (Monte Paterno, 2744 m). In the west, it continues via the Forcella Col di Mezzo (2315 m) to the crenellated peak (Col di Mezzo) (2254 m) and on to the 2252 m high cat ladder head (Croda d' Arghena).
