Buk is a village in Krumovgrad Municipality, Kardzhali Province, southern Bulgaria.

This place has an old pagan temple, a medieval fortress, and a tomb cut into the rock.

There's also a very old oak tree, over 200 years old, and some big rocks shaped like a crocodile, a mushroom, and a lion's head.

Two small holes in the rock that look like footprints are considered sacred and are known as "The steps of Ali."

Finally, around 25 km (15.5 miles) northwest of Bryagovets, in Stareyshino, you can visit the Dome Tomb called Punar Kaya.
