We will enter the Pulo di Altamura, one of the major karst testimonies of the Alta Murgia National Park. A truly unique scenario, a collapsed sinkhole with a diameter greater than over 700 m and a depth of approximately 90 meters with numerous caves, an ancient hermitage and a sinkhole. Magical place, inhabited by man since 5000 years ago, where cults were practiced in the Middle Ages and the Modern Age, evidenced by the findings of human remains, engraved pebbles and the precious fossil of the Cypraea shell. We will explore some of these dark places and then walk along panoramic rocky paths, among meadows of ferules and asphodels, under the flight of various species of birds of prey, including the kestrel and the migratory kestrel, and other birds. At the end of the excursion you can reach the historic center of Altamura to taste the famous Altamura bread, made with durum wheat semolina from Alta Murgia, cooked in ancient stone ovens and renowned since the Middle Ages.
