Great track, smooth concrete / asphalt. Lots of nature, no cars.
But it may be that occasionally the gates are closed so that the dyke nursing sheep do not run away. Either through (and close again) or use the dike crossings with stairs at these places to continue on the other side of the dike.
Kommoot had indicated this when planning the route. But I was surprised myself that there is also a way on the other side of the dike. Above all, I only saw him when I arrived at the St. Marien church in Warfleth. Piece back, stairs up and down, and then enjoyed beautiful nature! Attention e-bikers, because at the end of the route the dike has to be climbed at the latest, this means going up and down the stairs! Not so easy with a heavy bike.
