The vast Murgia plateau facing the Sassi of Matera constitutes the Regional Park of the Rupestrian Churches of Matera, which has also been declared a World Heritage Site since 2007. It is a large rocky hilly area marked by deep karst fissures called: “Gravine”. The show that appears before the eyes is truly breathtaking, since the whole inhabited area of the Sassi appears in all its splendour beyond the ravine. In a surprising and fascinating naturalistic context, following an initially somewhat steep path, accompanied by Environmental Naturalistic Guides, you descend towards the Gravina stream near which, in an area rich in vegetation, there is a characteristic Rock Church which " speaks to us” of the past. Looking up… the Sassi…. seen from the stream… amazement! Return to the Murgecchia plain and skirt the Gravina.
