SUP, for anyone who does not know what these 3 letters stand for: Stand Up Paddling. A sport which has been popular in Friesland for more than 10 years now. And a wonderful way of exploring South west Friesland. On your own or to train for the ultimate challenge: the 'SUP Elfstedentocht'. A traditional route of 200 km paddling through the 11 historical cities of Friesland.
