The Kraków-Kolna Canoe Slalom Course is an artificial whitewater course in Poland, on the south bank of the Vistula River, in the suburb of Kolna, 10 kilometres (6 mi) west of Kraków.
The top 120 metres (394 ft) of the course is a flatwater start pool that is covered in winter by a long white tent.
The flow diverters are two pairs of concrete wing dams and clusters of vertical blue and green plastic bollards attached to peg boards on the channel bottom.
To modernize the course for the 2013 European Championships, the top section was made shorter and steeper by extending the length of the start pool.
This change entailed raising the channel walls 70 centimetres (28 in) in the section above the foot bridge.
