Moravian Karst
The Moravian Karst is a karst landscape and protected nature reserve to the north of Brno in the eastern part of the Czech Republic, located near the town of Blansko. It encompasses a number of notable geological features, including roughly 1100 caverns and gorges and covers an area of roughly 92 km². Currently, five of the cave systems, Býčí skála Cave and Stránská skála are open for public tours and exploration.
This region is also home to one of the most important single geological features in the Czech Republic, the Macocha Abyss, a gorge 138 m deep, which was formed when the ceiling of a cave chamber collapsed. Macocha Abyss is also the place where the Punkva River begins to run underground through the Punkva cave system, and two small pools of water are visible at the surface.
The Moravian Karst is a popular tourist attraction in the local area, and large numbers of tourists visit in the summer months. In addition to caverns, the nature preserve contains well-marked bicycle trails and hiking paths to explore.
