The lake's water chemistry is influenced by its origin as a former chalk mine, resulting in high concentrations of calcium carbonate.
The basin is situated in a depression formed by geological mining excavation rather than natural glacial processes.
Despite its appearance, the lake does not have significant surface tributaries and is fed primarily by groundwater.
The intense turquoise color is an optical phenomenon caused by the scattering of light by suspended calcium particles.
The surrounding Wolin National Park contains the highest sea cliffs in Poland, located just a short distance from the lake's perimeter.
Jezioro Turkusowe is a post-mining pit located within the Wolin National Park on Wolin Island, Poland. Its name originates from the distinct turquoise hue of the water, caused by the reflection of sunlight off the white chalk-calcium bottom. The lake occupies the site of a former chalk mine that operated until the mid-1950s. The water level is dependent on groundwater, and the surrounding basin reaches depths of approximately 21 meters. The area is heavily forested, primarily with pine and beech trees typical of the Baltic coastal landscape. A network of walking trails connects the lake to nearby coastal cliffs and lookout points. It is a strictly protected natural site due to its ecological sensitivity. The water is mineralized and generally unsuitable for swimming, serving primarily as a scenic destination for hikers.
The Piaskowa Góra (Sand Mountain) lookout point provides the best elevated view of the entire lake basin.
Wear sturdy walking shoes to navigate the sandy forest paths surrounding the lake.
Bring binoculars for the Piaskowa Góra lookout to see the lake from a higher elevation.
Visit on a sunny day to ensure the turquoise color is most vivid against the white lake floor.
Do not attempt to descend the steep, unstable cliffs down to the water's edge, as it is dangerous and prohibited.
Stay on marked trails to protect the fragile cliff edges and forest ecosystem; swimming is prohibited.
