Switzerland, Lago di Sassolo

I discovered the Valle Sambuco in July 2015. The weather in Italy was very hot, so I decided to spend some time in Switzerland Alps near Locarno. So I discovered the wonderful Valle Maggia, Val Lavizzara and Valle Sambuco, three valleys in Canton Ticino between Airolo and Locarno. The superior part of the valleys is full ok alpine lake, some more big (Lake Sambuco), some very little (as Lake Sassolo, Lago Superiore, Lago Scuro, and many others).
