Dive-site story
Zimnik is a flooded former granite quarry in Lower Silesia, popular among Polish divers for training and recreational deep dives. Sheer granite walls plunge directly into dark waters, creating dramatic vertical topography with submerged ledges and industrial relics left behind from mining operations. Below the shallow layer, a distinct thermocline brings chilly conditions, requiring appropriate thermal protection throughout the year.
