In the Gioveretto Group which belongs to the Ortles Alps, a 70 hectares large reservoir is located at 1,850 m asl. Lake Gioveretto in the back Val Martello is used for energy generation (its hydro is located in Lasa in the Val Venosta) and is a popular hiking destination in summer.
An easy hike starts at the tavern “Zum See” at the end of the lake and proceeds along the Martello Valley Path to the dam wall and back again (2 hours). Information boards tell about the Stelvio National Park, surrounded by the majestic alpine world with its glaciers. There are the Vedretta del Cevedale and the Vedretta del Forcola glaciers, Mount Cevedale and the Cima Venezia, all more than 3,000 m high.
Also a demanding hike starts at the lake, it proceeds up to the 3,033 m high Cima Rossa di Martello peak (about 5 hours walking time). The lake is fed by the Plima, a river of the Stelvio National Park, which finally joins the Adige river. Inflows are the Rosimbach, Soybach and Flimbach streams. Due to heavy rain in 1987 the dam of the Lake Gioveretto had to be opened, 16 houses were completely destroyed.
