Valsolda Nature Reserve lies in the territory of the homonymous Municipality, on the eastern branch of Lugano Lake, and borders for a long stretch in the north-west with Switzerland and in the east with the Municipalities of Val Rezzo and Porlezza. The Reserve, situated between the 700m of the valley of the stream Soldo and the 1,810m of Cima Fiorina, represents a corner of wild and fascinating nature.
