With its 2,612 meters of altitude, Lago Vedretta is one of the most fascinating and impressive natural lakes of the upper Val Nambrone, in the heart of Trentino. It is the largest high‑altitude lake in the area, larger than the nearby Lakes of Cornisello (2,120 m), the scenic Lago Nero (2,233 m), and the more secluded Upper Vedretta Lake.
Lago Vedretta covers a surface that can exceed 87,000 m², with a length of up to 800 meters and a width of about 180 meters. These dimensions, however, vary throughout the year: the water level depends on snowmelt, precipitation, and meteorological factors that significantly influence the volume of the basin.
The presence of glacial silt gives the lake its milky, shifting color, typical of glacial lakes still in evolution.
During the 20th century, Lago Vedretta underwent water‑regulation interventions linked to hydroelectric production. This helped stabilize—at least partially—its capacity, while the lake continues to behave naturally and remains strongly influenced by the alpine climate.
From Lago Vedretta flows an emissary that descends into the valley and feeds the Upper Cornisello Lake, creating a hydrological connection of great naturalistic interest. The entire area is a mosaic of pristine alpine environments, shaped by glacial retreat and the force of water.
