The Danubian Plain is a Bulgarian wine region located in the hilly northern parts of the country. The vines of this wine region are planted on the steep valley slopes of the mountains, along the course of the meandering Danube River. Compared to other wine regions of Bulgaria, the Danubian Plains remain relatively underdeveloped. This means that the region is quiet in terms of tourism and tourist attractions but it is still certainly worth visiting. What the Danubian Plains lacks in terms of attractions it more than makes up for in terms of historical artifacts, ancient fortresses, and medieval castles.
