The Balcarka cave is situated in a picturesque karst valley near Ostrov u Macochy. The underground labyrinth of corridors, fissures and caves has two levels. The entrance portal of the cave is a significant paleonthological and archaeological locality. It is a place where bones of Pleistocene animals were found as well as stone and bone instruments and fireplaces of people of the Early Stone Age. Further parts of the cave were discovered in stages in the years 1923–1948. These caves can boast of unique, very rich, varied and colourful stalactite and stalagmite decorations. The parts called 'Gallery' and 'Natural corridor' are among the most beautiful sights of the Moravian Karst. Remarkable are also the circular abysses, the 'Rotundas'.
The guided cave tour lasts about 45 minutes and covers 700 m of passageway, including number of stairs. Bring a light jacket, as the cave temperature is about 8,7 °C (47 °F).
