This dive site, Montola, is a unique dive destination located in an old limestone mine in Finland, closed since the 1970s. Diving here is a privilege, offered exclusively at events organized by the Montola miners. Divers can explore open water sections, intriguing cavern areas, and challenging cave systems, offering a distinct topography shaped by mining history rather than natural marine processes.
The Montola mine is notable for its absence of fish, creating a starkly different underwater environment. However, it is renowned for amphibians that utilize the mine for spawning, offering a unique opportunity for macro observation for those with a keen eye.
The best time to visit Montola for diving is likely outside of summer months, as logs floating from the banks can sometimes affect conditions. Divers should be prepared for cold water typical of Finnish inland sites and be appropriately trained for cavern and cave environments to fully appreciate the unique geological formations and historical remnants of this fascinating underwater mine.
