The Borgio Verezzi Caves (Italian: Grotte di Borgio Verezzi), also named Valdemino, are a karst cave system located in the municipality of Borgio Verezzi, in the province of Savona, Liguria. They are a show cave.^[1]

Overview

Located in the outskirts of Borgio, the main town and seat of the municipality, the caves were discovered in 1933.^[2] The tourist route, opened in 1970,^[3] is 800 m (2,600 ft) long and features several small lakes,^[4] due to the presence of a little river named Rio Battorezza.
