The Trendelburg–Wülmersen run follows a curving section of the Diemel where higher riverbanks and woven channels cut paddlers off from road noise and daily life; alternating brisk current and calm pools weave together into an easy, approachable river day that finishes at the emblematic Wasserschloss Wülmersen.
