Matasvaara

Matasvaara is an expert-level dive site in Eastern Finland, featuring a flooded mine or quarry with extreme depth and overhead environments that demand the highest levels of training and equipment. The crystal-clear groundwater provides exceptional visibility, but the depth and confined spaces create serious risks for insufficiently trained divers. Cold, constant temperatures of 4-6°C require advanced thermal protection. The geological features of the flooded excavation — vertical walls, tunnels, and submerged machinery — create a haunting industrial landscape unlike any natural dive site. Matasvaara is strictly for technical divers with full cave or mine diving certification and proper redundant systems.
