We meet at the Wadden Sea Centre where we find bicycles, if you are not bringing your own. From here, the guide will take you on a 17 km round-trip in the Wadden Sea National Park. We bike in the area of the old border between Denmark and Germany in the period 1864-1920. We will pass dikes, marsh areas and ditches where we might be lucky to see wading birds and ducks. We make short stops during the trip, to experience the old border district and hear about the birdlife and the history hidden in the landscape. We take a break at Hviding Engsø and enjoy coffee and cake.
