The largest and most beautiful karst area in central Europe is a place where visitors have their breath taken clean away. The main attraction here is the famous Macocha Abyss, some 138m deep and steeped in terrifying myths and legends. Without doubt the Moravian Karst is one of the natural wonders of the Czech Republic, which will wow every visitor.
