The dominant feature of the central part of the Moravian Karst is the Rudice Sink, where the waters of the Jedovnice Stream disappear beneath ground before emerging to the surface again after a twelve-kilometre journey through the mysterious subterranean world at Býčí Skála in Josefov, where the famous bronze statue of a bull was found. The typical karst canyons of Pustý Žleb and Suchý Žleb (Desolate Glen and Dry Glen), the Bílá Voda (White Water) Depression and, in particular, the Amateur Caves, which are not open to the public, are also remarkable.
The great abundance and wide range of karst formations and the rare fauna and flora here are provided with strict protection. This, the largest and most highly developed karst area in the Czech Republic, was declared a protected landscape area in 1956. The most valuable localities are offered additional protection in fourteen nature reserves that are home to numerous unique examples of living and mineral nature. The bottom of the Macocha Gorge, for example, is the only place in the country where the rare flower Alpine bells (Cortusa matthioli) grows. The subterranean karst is the winter home of bats – typical representatives of cave fauna.
