The park contains the largest gypsum karst formation in Italy, recognized for its scientific importance.
The Spipola Cave system features an underground river and a complex series of galleries accessible only through guided tours.
The gypsum landscape is particularly susceptible to erosion, constantly reshaping the park's topography through rainfall.
The park is a UNESCO World Heritage site nominee due to the exceptional value of its evaporitic karst landscape.
The diverse microclimates within the sinkholes, known as 'doline', allow for the coexistence of both woodland and Mediterranean plant species.
Historically, the local gypsum rock, known as 'selenite', was extracted and used extensively in the architectural construction of medieval Bologna.
Parco dei Gessi Bolognesi e Calanchi dell'Abbadessa is a protected regional park situated on the first hills southeast of Bologna. The area is defined by a unique geological formation of Messinian gypsum, which has created a widespread landscape of sinkholes, karstic cliffs, and deep ravines. Beneath the surface lies an extensive network of caves, including the Spipola Cave, which is one of the most significant gypsum karst systems in Europe. The Calanchi dell'Abbadessa section consists of dramatic, barren clay badlands formed by intense erosion. The park covers approximately 2,000 hectares of diverse terrain ranging from 70 to 400 meters above sea level. It serves as a natural habitat for numerous bat species, amphibians, and diverse Mediterranean flora. Visitors can explore a network of marked hiking, mountain biking, and equestrian trails that traverse the gypsum ridges. Several historical sites, such as the remains of rural settlements and old quarries, are scattered across the protected landscape.

Wear sturdy hiking boots with excellent grip, as the terrain is uneven and can be slippery in clay areas.
Download the park's digital trail map before arrival, as cellular reception is inconsistent in the valleys.
Bring a windbreaker or light layer, as temperatures in the sinkholes can be significantly cooler than on the surrounding slopes.
Do not attempt to enter caves without a registered guide or proper authorization, as the gypsum karst is unstable and hazardous.
The Spipola Cave is open for scheduled visits only, typically requiring advance booking through the visitor center.
Stay on marked trails to avoid damaging fragile clay badlands and trespassing on private agricultural land.
