Through the castle park, start the ascent along the Syr, past a waterfall into the Manternacher Fiels nature reserve. You pass the ruins of an old wooden mill. Over the Meschelslay and some stairs up, you reach a wonderful viewpoint. Follow the path downhill through the Schlaufels forest area to the wild stream of the Schlammbach. Then you ascend again and return over the height of the Widderberg back to Mertert.

In Mertert, where the Moselle and Sauer rivers meet, a fountain and an old-fashioned pavilion provide romance along the culture trail. The park also offers an outdoor fitness course, a boules court, a tree adventure trail, a playground and water playground, and much more. Events and concerts are held all over the year in the idyllic park.
