Parco dei Gessi Bolognesi e Calanchi dell'Abbadessa

It is a deep blind valley developing at direct contact with very inclined chalky strata; at the bottom, the swallow hole access to Calindri Cave (another protected cave) opens. While the southern slope is gentle, with cultivated fields and a small vineyard, the opposite slope is very steep. The outcrops are colonized by the characteristic pioneer vegetation consisting of moss, lichens, and small succulent plants; in summer, the golden helychrisum and broom bloom. The bare areas alternate with a low shrub formation of Downy oaks, where the evergreen phyllirea also appears.
