The caves are considered the most colourful in Italy due to the rich iron and manganese mineral deposits in the limestone.
The cave system was discovered by a group of local youths who noticed a small hole in the ground during a flood event.
Bones of extinct Pleistocene-era animals, including the saber-toothed tiger and cave bear, were discovered within the cave sediment.
The cave is formed in 'Verezzi limestone,' a type of rock dating back to the Miocene era.
Unlike many caves that are completely dry, the active water seepage creates constant, slow-moving calcium carbonate deposits.
Grotte di Borgio Verezzi is a karst cave system renowned for its exceptionally high concentration of diverse minerals, which create vibrant red, yellow, and white crystalline formations. Discovered in 1933 after heavy rainfall exposed an opening, the cave system was opened to the public in 1970. The route spans approximately 800 meters, guiding visitors through chambers filled with stalactites, stalagmites, and translucent draperies. Groundwater percolation continues to shape the cave, sustaining its active status. The site is located in the Borgio Verezzi commune, separate from the historic hilltop village of Verezzi. The temperature inside remains constant at 16°C throughout the year, regardless of external conditions.
The main cavern featuring the largest concentration of orange and red mineral-stained stalactites.
Wear a light jacket or sweater regardless of the season, as the cave temperature is constant.
Wear closed-toe, non-slip footwear as the ground can be damp and uneven.
Book your visit in advance during peak summer months or public holidays to guarantee entry.
Avoid arriving without checking the website for group booking availability, as guided tours operate on specific group rotations.
Closed on Mondays during the off-season. Consult the official website for annual maintenance closures, which typically occur in late autumn.
Do not touch the rock formations, as oils from human skin can stop their natural growth and discolour the minerals.
