In the northwest of the region of Sankt Wendel we finde the municipality of Nonnweiler. The Celtic Ringwall at Otzenhausen, which is also known as “Hunnenring”, is of national importance. Built in the first century before Christ, even today 10 m high walls tell of the monumental memorial. Excavations, regular guest tours, workshops and archaeological seminars invite you to visit the site.
The Primtalsperre (Prims Dam) has created a recreational area which is characterised by its naturalness. Embedded into the hilly landscape you can superbly cycle or hike along the 13 km long circular trail.
The summer toboggan-run with the sliding paradise on the Peterberg mountain is a highlight, particularly for children. Several types of slides and the 1 km long toboggan-run offer pure driving pleasure.
Interesting theme hikes, such as the planets or archaeological hike offer a lot of information. The hiking on the Saar-Hunsrück-Steig is in any case a special nature experience. The cycle path "Saarland-Radweg" leads through the community.
Parts of the municipality belong to the new Nationalpark Hunsrück-Hochwald.
