They call it the Valley of Pink Pants. But this affectionate nickname of a toponym refers to just one village, set inside a pocket of the western Rhodope: Ribnovo. Ribnovo sits at 1,152 metres above sea level, but this is not the only reason for its image as a bit of a fortress and a destination for the culturally curious. As a friend put it before we visited: Ribnovo is another planet. He was from Breznitsa, a toned-down version of Ribnovo, right across the Mesta Valley, so he should know.
