The Pravets monastery is a very famous one. This small monastery is located 3km away from the town of Pravets.
A former Thracian sanctuary turned to a Christian closter at the time of the Bulgarian Tzars Assen and Petar, destroyed in the 18th century and rebuilt soon after that.
The monastery does offer accommodation.
From the monastery starts an eco-path, so it is a nice place for spending the weekend.
