Le vallon du Nideck est un site historique connu notamment par la légende des géants du Nideck. Il rassemble quelques espèces rares en Alsace comme la biscutelle, et un des plus vieux peuplements d'if. La forêt entourant le château est une hêtraie sapinière.
Le château du Nideck est situé le long de la Hasel près de Oberhaslach
