Excursion to the Frasassi Caves
Bonelli Bus will take you on the discovery of the wonderful Frasassi Caves. These caves of karst origin are in the Regional Nature Park of the Gola della Rossa and Frasassi in the municipality of Genga.
The main entrance is in the “Grotta Grande del Vento”, which was discovered in September 1971 by Rolando Silvestri and the “Gruppo Speleologico Marchigiano di Ancona” (Cave explorers group from Ancona). The entire complex can be partially visited, as 13 km of trails can only be accessed by scholars and experts. The galleries that are open to the public offer a majestic natural spectacle and an easy and evocative tour that attracts many visitors each year.
