Lago del Sambuco is a high mountain reservoir at an elevation of 1.435m (4,708ft) above the sea level, located in the district of Leventina in the canton of Ticino in Switzerland.
The road to the lake is outstanding. It’s one of the scariest roads in the country running on the eastern shore of the lake. Imagine what it must have been like before the barriers. Starting from Lavizzara, at 760m above the sea level, the climb to the reservoir is 11.1 km long. Over this distance the elevation gain is 675 meters, and the average gradient is 6%, but some sections are up to 10%.
The road includes a fabulous series of 12 hairpins as the road gets steeper. The most challenging part of the road is a three flat kilometres section beside this large lake.The road goes on to Lago del Naret.
