Castelluccio's valley is a big plain in between the mountains, 1000 meters above the sea level.
In this valley in between the mountains there's nothing. No solid buildings, no fences, no roads, nothing human. There's just grass and flowers.
We were there early for the traditional blooming, when this valley dress itself with the colours of thousands flowers, yellow red and blue.
We had that walk from Castelluccio to the feet of this mountain, we started like a small walk and then we realized it was a 3 kilometers walk, and hour and some more :D
