Calm freshwater quarry lake for easy shore diving.
Calm freshwater quarry lake for easy shore diving.
Mrowiny is a calm inland quarry lake between Mrowiny and Żarów, with a shallow, plant-filled edge and a simple shore-entry profile. Divers come here for easy freshwater practice, fish among the weed beds, and an underwater basin that opens up beyond the littoral zone. It is best treated as a straightforward local lake dive rather than a dramatic or current-heavy site.
