The pearl routes are interactive walking routes. Due to circumstances, the pearl routes can currently only be found in an adapted way on this website. Below you will find the text and the link to accompanying videos that you can watch on the way for the relevant topics. There are both Dutch and German (DU) videos available. We wish you a lot of fun during your walk!
During the flood disaster, the seawater flowed in and out of the polders, eroding deep gullies. The dikes have now been closed, but the water in the gullies has remained. That is why beautiful creeks have now formed here, where you can find birds and other animals. You might even see a lizard dart away. In the water, you can also find fish such as the eel, the flounder, and the rainbow trout. This fish can be recognized by its black spots. But there is one place on its body where there are no spots. Follow the route and look around carefully, and you will learn more about the rainbow trout.
Question 4: Where on its body does it have no spots? Take the 2nd and 3rd letter of the answer.
