Above Manderen stands the Église Saint-Étienne, which replaced a church dating from 1618. The nave and choir are believed to have been built around 1776; the bell tower is dated 1894. Its richly carved furnishings include a stone high-altar retable from the transitional period between the late Renaissance and early Baroque, as well as several statues.
When planning a stay in Manderen, the wish to rent a holiday apartment can be taken into account as a separate item.
Hiking
The Circuit de Malbrouck is a challenging 14-kilometre circular hike with a stated duration of five hours. This outdoor walking route begins in Manderen-Ritzing and combines historical and natural themes. The Circuit de Malbrouck is signposted.
The Chapelle de la Paix is highlighted along the Circuit de Malbrouck as a place of understanding between peoples.
Nature
The Ravin du Diable can only be visited outdoors and independently via marked paths. The Résurgence du Husprung is a Vaucluse-type karst spring and a resurgence of infiltrated water, where visitors can observe the water emerging from the ground.
The Ravin du Diable is an important attraction in the forest of Manderen and consists of a depression containing a pond. It is associated with the legend that Arnold VI de Sierck sold his soul to the devil in order to complete the construction of his castle.
