About Montola
Montola is a flooded limestone mine in Pieksämäki with open water, cavern sections, and caves that make it a limited, event-based dive rather than a casual recreational site. It is known more for technical overhead diving than for fish life, with stable freshwater, handrails, and strong planning needs around access, training, and the seasonal visibility swing.
