For its historic village centre and its valley location, locals call Gemünden the Pearl of the Hunsrück (Perle des Hunsrücks). Standing above the Simmerbach is Schloss Gemünden, a residential castle still used as a private home today. A good two kilometres south of Gemünden stands the Castle Koppenstein ruin on the Koppensteiner Höhe, a 555 m-high hilltop in the Soonwald. Five kilometres to the east is the Alteburgturm, a lookout tower on the Alteburg (mountain). Southwest of Gemünden is the Lützelsoon plateau.
