It took a while before I discovered that the common name of this waterfall in St Christina Val Gardena is cascata Tervela. Cascata Tervela is a beautiful 30-50 meter high waterfall near the skilift of Monte Pana, near the city centre of St Christina.
From the parking of the skilift Monte Pana it is a short walk to Cascata Tervela, sometime also referred as cascate del Monte Pana or named after a trail Raida dl Luech. The trail is passing the bottom of the waterfall with some good viewpoints.
I have seen several nice pictures of the waterfall but I can’t find any river on maps. So I think the waterfall is only visible in springtime and early summer.
