The Moselle department labels this episode as part of its protected natural areas series and names the former saltworks at Château-Salins. It is regional landscape context for Gréning, not proof of a trail or filmed scene inside the commune; use local route records for access details.

This departmental film identifies the Étang de la Mutche at Morhange, a separate wetland in the surrounding Moselle East area. It can help frame the region’s water and habitat landscape, but it must not be mistaken for a video of Gréning or a description of its forest access.
The title presents walks across Moselle East rather than a single village itinerary. Gréning sits within this wider eastern Moselle setting, so the clip is regional orientation only. It does not establish a marked route, current trail condition or any opening schedule in Gréning.
