Breggia is a Swiss-Italian river. The springs are around the Monte Generoso and Monte d'Orimento in the Val d'Intelvi at an elevation of 1389 m. It enters Swiss territory between Erbonne and Scudellate, and flows along the Muggio Valley until Chiasso/Vacallo, where it again enters Italian territory, in Maslianico. Breggia then drains into Lake Como, near Villa Erba between Como and Cernobbio at an elevation of 198 m.
