With a temperate climate Bulgaria has the perfect growing conditions for an array of grape varieties.  Wherever you travel, south facing slopes are a collage of manicured rows of vines.  Melnik is one of the most famous growing areas in South-Western Bulgaria and combines an historic old town, the famous Melnik Pyramids (natural sandstone rock formations found only in this area) and numerous chateaus dating back centuries.  Tours of the vineyards and cellars along with wine tasting trips can be arranged.
