Borgio Verezzi Caves

Borgio Verezzi Caves form an underground system extending about 800 meters beneath the surface with natural chambers and small pools. These pools were created by the Rio Battorezza stream, and the rock walls display mineral deposits that create colorful patterns throughout the passages.

The cave system was discovered in 1933 and contains prehistoric bone remains dated between 500,000 and 750,000 years old preserved in its chambers. These archaeological finds reveal that early humans inhabited this area during the distant past.

The caves sit along a walking trail that tells the geological story of Liguria through panels and signs placed throughout the landscape. This path connects the underground chambers with the surrounding hillside, helping visitors understand how the region was formed and shaped over time.

Guided tours run throughout the year, and the temperature inside stays constant at around 16 degrees Celsius (60°F) regardless of weather outside. Since it remains cool year-round, visitors should bring a jacket even on warm days above ground.

The caves hold Italy's longest recorded straw formation, a thin mineral structure that extends several meters in length. This rare mineral feature formed as water slowly dripped and deposited minerals, creating the distinctive threadlike shape that makes it stand out from other cave formations.
