It is set in the north-eastern scree of the Croda dei Toni, a short distance far from the Forcella Giralba, in the heart of the Dolomites of Sesto.
From Sesto, in Val Pusteria, go as far as the Capanna di Fondo Valle and then continue along a mule track as far as a junction. From here go ahead as far as you arrive under the rocks of the Pulpito: as you go around a spur you will see the Croda dei Toni. You can reach the Rifugio Zsigmondy-Comici and the lake in about 15 minutes.
The "strada degli alpini" (route of the Alpine troops): only for experts!
From the lake turn left along a path which climbs quckly; go along the rocky spur of the Cresta di Zsigmondy and enter the Cengia della Salvezza. Cross the snowfield of the Busa di Fuori. The ledge continues crossing the western wall of Cima Undici and arrives at the homonymous pass; here the route of the Alpine troops continues but becomes more binding, so you can leave the path and continue to the Alpe Anderta and eventually to the Capanna di Fondo Valle.
