A geotourist route through the Geosites of Cinisi and Terrasini cliffs

Abstract

This study evaluates the scientific relevance, quality, and sustainability of a proposed coastal geopath extending for approximately 7 km along the Tyrrhenian coast of northwestern Sicily, between Torre Mulinazzo and Capo Rama, near the towns of Cinisi and Terrasini (Sicily, Italy). The area is characterized by a highly irregular coastline formed by alternating rocky cliffs and sandy beaches, shaped by differential erosion and active tectonics. This geomorphological diversity results in a complex and scenic coastal landscape that hosts significant geological features. A total of 20 sites of geological interest were identified, including three officially recognized geosites and two proposed ones. These sites represent a stratigraphic succession ranging from the Upper Triassic to the Lower Pleistocene, with depositional environments transitioning from shallow to deep marine settings. The proposed route allows for a comprehensive interpretation of the lithostratigraphic, structural, and geomorphological framework of the area within a compact and accessible sector. A quantitative assessment of the geosites was carried out using two established methodologies: the Geosite Assessment Model (GAM) and the method developed by Feuillet & Sourp (2011). Results highlight the high scientific value and uniqueness of the majority of the sites. Only a few, such as the more common beach sectors, scored lower in terms of scientific relevance. Most sites also demonstrated high additional values, including accessibility, aesthetic appeal, and educational potential, due to their proximity to urban centers and supporting infrastructure. Despite urbanization, the presence of protected areas and environmental constraints has helped preserve natural features. The study confirms that the proposed geopath holds strong potential as an outdoor educational laboratory and a sustainable geotourism resource. The development of sea-based services is recommended to enhance accessibility to coastal sites not reachable by land, fostering broader community involvement.
