Karls Erlebnisdorf is a small theme park of children in Zirkow on Rügen. Everything is themed around strawberries, and the gift shop sells a number of unusual strawberry-based items such as strawberry pasta and mustard.
Last year when we visited it was so hot, that we decided not buy any strawberry jam and have it in the car for several days with temperatures above 30°C, so being on the island this week I went back and stocked up.
