AZS Wilkasy Marina

Nestled on the western shore of Lake Niegocin in Wilkasy, this is one of the largest marinas in Mazury, with berths for up to 280 yachts and 4 cruise vessels. It's run by Poland's Central Academic Sports Centre, so the setup is seriously well-equipped — you can rent kayaks, paddleboats, windsurfing boards, rowing boats, and regatta yachts right on site. The whole complex operates year-round, which is pretty rare for this part of Poland.
