The swimming area is nearly circular and makes an impression with is crystal-clear water. It is no surprise that the Polish Balaton has become a favourite spot for local residents. You can rest here, swim, dive, and fish. Climbers can try their skills on the steep rocks protruding above the water. The reservoir was created after the extraction of limestone ended in the 1960s. In the summer it serves as a swimming site and part of it is used by the Polish Angling Society – Trzebinia Branch and the Diving Club. Originally, there was a hill rising to about 346 metres above sea level composed of Jurassic limestone (remains of sponge reefs can be seen in the characteristic granular structure of the rocks).

It is a great place to take a walk and catch your breath. As a result of natural processes, a forest dominated by birch trees has grown on parts of the former excavation site, while amphibians and moisture-loving plants have moved into the small fens. In the southern part of the reservoir, there is a large beach with swimming facilities, while steep rocks tower over the water in the northern part, attracting fans of rock climbing. The water in the Polish Balaton is crystal clear, as it is fed by underground cold springs. The clarity of the water encourages diving. At the bottom of the reservoir, you can see sunken railway tracks, a mining wagon, and yacht wrecks. You can spend time attractively not only underwater but also on the surface! Bayer Park is an inflatable water park, i.e., an obstacle course, slides and other inflatable structures on the lake, which are a fun way to challenge yourself, and it's for everybody, not just the little ones! In addition, Bayer Park ican also be found in several other swimming pool areas. It is well worth a visit as by collecting stamps every sixth entry is free! 

The lagoon isn't just an opportunity to refresh yourself in the crystal clear water; the bathing area offers many attractions for the whole family. The picturesque beach provides excellent conditions for sunbathing and relaxation, while numerous picnic areas make it a wonderful place to get together for a cookout with friends and family. For those who are active, sports fields, water bike rental and walking trails run along the lake shore. There is also a refreshment stand at the bathing area, where you can enjoy finger-licking treats and refreshing drinks.
