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]
Located in the outskirts of Borgio, the main town and seat of the municipality, the cavese were discovered in 1933.[2] The touristic route, opened in 1970,[3] is 800m long and counts some little lakes,[4] due to the presence of a little river named Rio Battorezza.
The Valdemino are touristically defined as "the most colorful show caves of Italy",[5] due to the presence of various minerals. Main colors are white, yellow, red and related shades. The cave contains many straws, amongst them the longest known of Italy with 2.5 m length.
Some prehistoric bone remains, dated between 500,000 and 750,000 years ago, have been found in various hollows.[6]
