Cascata di Santa Petronilla is a hidden gem near Biasca in the region Ticino, Switzerland.
When driving on highway 2/E35 take the exit Biasca. Drive to the city centre and park the car somewhere in the centre, if possible near the church “Chiesa Ss. Pietro e Paolo” (gps 46.359811, 8.972226). Here a hiking trail starts but you also can start at the trail in front of the other church (Via Santa Petronilla), there are small yellow signs.
In 30 minutes time you walk to the lower part of the waterfall, Cascata di Santa Petronilla, although there is also a last drop near the train station itself (Via Officina). Back to the other trail: one of the nicest pictures I have seen is with the old stone bridge above the waterfall. You can walk up along the waterfall to see more of Cascata di Santa Petronilla. It is said that this waterfall is the highest waterfall in Ticino with a total drop of 260 meter!
Nearby you can find another scenic waterfall called Cascata del Pozzón, in Osogna.
