[2] Located about 30 km (18.6 miles) northeast of Gruevo, Perperikon is a medieval structure that is thought to have served as a Thracian sanctuary for the Roman god Dionysus.

The Thracian sanctuary known as Orlovi Skali is approximately 41 km (25.5 miles) west of Gruevo, close to the neighboring village of Ardino.

This site features 97 carved rock niches in the cliffs, which were used to place votive offerings by the cult of the dead.

Their pink hue is due to the mineral kloinoptilolit, while blue and black spots are from manganese nodules, and greenish tones come from celadonite.

This spot, located in a deciduous forest, this peak features a high rock cliff and a fountain with several spouts at its base.
