The book comprises 15 natural, cultural and historical sites that for some reason have remained away from the beaten track of popular interest or have merits of which the general tourist, be it a Bulgarian or a foreigner, is largely unaware. Hidden Treasures of Bulgaria 1 takes the reader on a journey from Valchanov Bridge in the Strandzha to Pravets, the birthplace of Communist dictator Todor Zhivkov, while passing through fascinating places like Yaylata Plateau, the mouth of the Rezovska River, the Belogradchik Rocks, and more.
