Near the Yasna Polyana dam is this beautiful natural formation located on the Dyavolska river.

We visited it in early April when nature was waking up. Primroses and many other beautiful spring flowers were in bloom all around.

The Devil’s River, 37 km long, is located in southeastern Bulgaria and flows into the Devil’s Bay on the Black Sea.

The river originates from a spring-fountain at 440 m above sea level. under the name Dudenska river in the ridge of Bosnia.
