Lago di Lucendo
Lago di Lucendo is a high mountain reservoir at an elevation of 2.184m (7,165ft) above the sea level, located in the municipality of Airolo of the canton of Ticino, Switzerland.
The road to the reservoir is gravel, narrow, steep and pretty bumpy. The road is usually impassable in winters. Stay away if you're scared of heights. The reservoir was built in 1947.
