These hills planted with orchards and vineyards producing renowned wines are on the south flank of the Carpathians. Beyond Buzau (heading towards Brasov), floral villages sit in a verdant landscape punctuated by treasures like Ciolanu monastery (16C). Don't miss the hamlet of Colti, known for black amber, and Alunis with its cave hermitages (14C-16C). Around Berca, discover also the area of mud volcanoes, where the earth disgorges large gas bubbles, and follow the lovely Slanic Valley.
