Abisso Bonetti

Abisso Bonetti ("Bonetti Abyss") is a Karst cave in the municipality of Doberdò del Lago (Gorizia, Friuli-Venezia Giulia, Italy), 1 km (0.62 mi) SE from the small village of Bonetti, near Slovenian border (village of Nova vas). The cave is one of the most famous cavities in the Gorizia Karst. Anyway, due to its dangerous pit opening, entry is allowed only to expert cavers with the necessary equipment for single-rope descend.
