OK. I am going to boast a bit about my own village
These are two waterfalls I have some 40 min walk away from my house
Cova de les Gralles
La Pixera (read "pishera" from "pixar"="to piss"), one windy day that made the fall flow upwards!
Unfortunately, the "cova de les Gralles" waterfall happens only some 12 days a year, and the "Pixera" reverse is even rarer.
Greetings,
Josep
