An artificial lake on the river Drava created in 1978, Lake Ptuj is actually the largest artificial lake in Slovenia, covering 420 hectares. Whilst its primary function is that of a reservoir for the nearby power plant, fun and games were always going to spring up on such a site. A popular place for rowing and sailing, the lake plays host to many national and international events, including the National Kayak Championships. Marina Ranca, the only land marina in Slovenia, is found here, and Ranca Bar provides visitors with refreshments into the early hours. It is also home to hundreds of endangered bird species.
