View of Bostalsee from the dam

Highlight • Viewpoint

The Bostalsee is a reservoir in the municipality of Nohfelden in northern Saarland, which was accumulated in 1979. The dam has a length of 500 meters. The lake is almost exclusively for recreational use. The dammed water power has been used to a limited extent since the end of 2013 to generate electricity, especially in order to illuminate the circular route around the lake during the winter months. The south-western part of the lake is designated as a nature reserve. There are two beach baths, a boat rental, petting zoo, bike rental, catering and much more.

Nonnweiler Reservoir

Highlight • Lake

Definitely worth a detour. Due to the nature reserve and bathing ban, nature is untouched here and the widely ramified reservoir with its many shelters offers a great view in every season.

Embedded in the wooded high forest landscape, the Nonnweiler dam with its 12.8 km long circular hiking trail is a paradise for cyclists, hikers and nature lovers of the Saarland. Its task is to hold back excess water from the prims so that they can be used for the various areas of water management. The supply of the population with drinking water was in the foreground of the considerations to build a dam in the deep valley above the locality of Nonnweiler.

The dam at Bostalsee is an impressive structure that dams the largest artificial recreational lake in southwest Germany. The dam not only serves an important function for water sports and leisure activities, but also offers a wonderful view of the lake and the surrounding landscape. With its length of around 500 meters and a height of 20 meters, the dam, which was completed in 1979, is an impressive structure. A walk across the dam is particularly recommended at sunset, when the light bathes the lake in warm colors.
