Over the millennia, the territory of Alta Murgia National Park has been shaped by erosion phenomena. The canyon of Gravina in Apulia, sloping down towards Matera and Bradano, marks the south-western border of the protected area. Near Altamura, you will find the impressive karstic Pulicchio and Pulo dolines, respectively of over 100 and 70 meters of depth. Although the Park landscape has been transformed over the centuries by man, Alta Murgia preserves a fauna and flora of great interest.
