Sosina, reservoir in Poland
Sosina is a man-made reservoir near Jaworzno in southern Poland, featuring two sandy beaches and shallow water along the shore. A paved path runs around the entire basin, and the surrounding area includes shaded spots, a playground, a volleyball court, and a boat rental service for pedal boats and kayaks.
The reservoir was formed after sand was extracted from the ground during the coal mining era that shaped the Jaworzno region for decades. When mining activity declined, the pit gradually filled with water and was later developed into a leisure area open to the public.
The name Sosina comes from the Polish word for pine forest, reflecting the tree-covered surroundings of the area. On warm days, families and young people gather here to picnic, swim, and spend time outdoors in a setting that feels close to nature despite being man-made.
The site is on the outskirts of Jaworzno and easy to reach by car, with parking available near the beaches. The path around the water is flat and open to walkers, cyclists, and skaters, and you will find changing rooms, restrooms, and food trucks close to the swimming areas.
A small island sits in the middle of the water and is unreachable for visitors, which has made it a nesting ground for waterbirds. This natural colony established itself on its own in a space that was originally shaped by industrial sand extraction.
