Lago Blu

The Lago Blu sits at 2,220 metres in a morainic hollow at the foot of Monte Rosa, whose turquoise water contrasts with the glaciers of the Monte Rosa massif.

Why it matters

The lake is a small glacial body of water whose colour shifts from milky green to deep turquoise, framed by the great pyramid peaks of the Monte Rosa group. From the plateau above the lake, the view opens onto Castore, Polluce, Roccia Nera and the Breithorn. The surrounding landscape includes the Verra glacier and the high peaks of Monte Rosa.

What to notice

• The lake is fed by glacial water, which gives it its characteristic colour.
• The surrounding landscape includes the hamlet of Fiéry, Pian di Verra Inferiore and the Evançon stream.
• Castore and Polluce, twin summits of the Monte Rosa group, rise with Roccia Nera and Breithorn above the plateau.
• The Verra glacier's moraines form part of the surrounding landscape.
