Cascata di Santa Giulia (also known as cascate di Rescia) is a 70 meter high waterfall at the beautiful caves of Rescia (grotte di Rescia). The waterfall is located at Rescia, lago di Lugano, not far from Osano in the region Lombardia, Italy.
There is a small parking at the camping site (gps 46.013779, 9.105287). Cascata di Santa Giulia is located a little up the mountain. Along the road (you have to walk a little back) you see an unnamed waterfall. Here a path must run up the mountain to Cascata di Santa Giulia and the church of Giulia (although I can’t find it on Google map).
I think the volume is very seasonal. In wintertime the flow is respectable, in summertime it probably runs dry but after a heavy rain shower the waterfall can very impressive. This region is known of its heavy rain showers in summertime, so the day after would be perfect to visit Cascata di Santa Giulia.
