The pier, the borrowed boats and the little beach facilities

The centrepiece of the beach is its pontoon pier, a recent addition that has become a favourite hang-out for young people and a good spot to sit over the water and take in the lake. Around the shore you'll find the modest extras that make a half-day comfortable: clean raked sand, a basic toilet, an outdoor gym with a few exercise stations, and a small wooden children's play area with swings and a playhouse—enough to keep kids busy between swims.↗↗

The best value on a summer weekend is the free watercraft. In recent summers the Aleksandrów Kujawski municipality has lent rowing boats, kayaks and pedal boats to beach-goers at no charge, typically on Saturday and Sunday afternoons through the holiday season, handed out on site by a local caretaker. Availability shifts from year to year, so it's worth confirming on arrival—but when it's running, paddling around the calm lake is a memorable, cost-free way to spend the afternoon.↗↗

Visiting: swimming, parking and what to bring

This is an unsupervised bathing spot, so there are no lifeguards on duty and you swim at your own responsibility—keep a close eye on children, and don't dive or jump off the pier. Water conditions vary with the weather and the season: visitors note that the lake can take on a greenish tinge, with more algae gathering on one side of the pier while the other stays clearer and more pleasant for swimming. The far bank and open fields give it a calm, rural atmosphere that regulars describe as a small oasis of quiet.↗↗

Practically speaking, the beach is small and intimate rather than a large organised resort, and there is no food kiosk or shop on the sand—bring your own water and snacks. Parking is easy enough, with space near the sanctuary just a short walk from the water. The beach itself is open around the clock, but the swimming, boats and playground are very much a warm-season affair, so plan your visit for the summer months.↗↗

Where it sits and what else is nearby

Ostrowąs lies in the Aleksandrów Kujawski district of the Kujawy-Pomeranian Voivodeship, an easy detour if you are based in or passing through this central-Poland lake-and-spa corner of the country. The spa town of Ciechocinek, with its own riverside beach on the Vistula, is only around ten kilometres away, and larger draws such as Toruń, Inowrocław and Włocławek are within easy driving range, making the lake a pleasant low-key stop alongside a wider regional itinerary.↗↗
