In general, it's fine, there are pros and cons everywhere.
It's great that on a hot day you can swim and swim in the cool river! But... The sand ends a meter from the shore, and then a dirty muddy bottom with mussels, algae and periodically floating boats from coast to coast, a patrol forbidding swimming behind buoys, burning sand and little shade.
On the other hand, there is an opportunity to sit by the water, in nature, there are changing rooms and a toilet. And for 1p. you can go by boat to the other shore and walk along the embankment or in the park.
Unfortunately, it's getting worse and worse. Both the beach and the river are overgrown with grass, the sand from the beach is washed away by rain, the pine has probably not been cleaned since the Soviet era! There are NO pleasure boats, the recreation park is in a depressing state... And this is the "pearl" of the Belarusian Polesie!
