Starting from the end of the Antholzertal / Valle Anterselva Lake turn right and follow the mark n. 7 to the Steinzgeralm hut. Short hike on an alpine path and way back to the lake on the forest road.
From the Steinzgeralm you can walk on for half an hour reaching the “Obere Steinzgeralm” at 2076m or further the Staller Saddle (path n. 7). For your way back take the path n. 11.
