The Schlickschlitten sleds are unleashed on the mudflats just once a year here – the Wältmeisterschaft & Ostfriesischen Wattspiele Schlickschlitten races are held in mid-summer every year. The special sleds, which were once used by fishermen to drag their haul across the tidal mudflats and empty out their nets on land, are ridden along marked-out routes. Tasks are completed and, sometimes, a quick game of football is played on the Wadden Sea’s tidal flats at the end. The Schlickschlitten races are not just designed for experienced ‘tidal flat pros’ – anybody can take part and tell their loved ones back home about the East Frisian carnival on the tidal flats. They may even get to brag about the trophy if they win!
