The forestry office looks after not only the State Forest but also twelve municipalities’ woodlands in the south of the Limburg-Weilburg and Lahn-Dill districts.

The other Ortsteile (with 2021 population) are:[3] Until about 150 years ago, Heinzenberg, which now belongs to Grävenwiesbach, was also one of Weilmünster's constituent communities.

During Nazi Germany, the mentally ill and handicapped of the 1897 Landesheil- und Pflegeanstalt Weilmünster (English: State Medical and Care Facility) were forcibly sterilized and systematically underfed or killed with drug overdoses.

Of today's constituent communities, Möttau had its first documentary mention in 802, Laubuseschbach in 897, Wolfenhausen in 1194, Essershausen in 1233, Lützendorf in 1234, Dietenhausen in 1301, Ernsthausen in 1309, Laimbach in 1344, Langenbach in 1335, Rohnstadt in 1355 and Aulenhausen in 1565.

The municipal election held on 14 March 2021 yielded the following results: The community's arms in their current form were conferred on 1 July 1935 by the Chief President (Oberpräsident) of the Province of Hesse-Nassau and on 30 September 1983 they were confirmed by the Hessian Minister of the Interior.

This provincial town is situated at the mouth of the Thorne in the Eyrieux, a tributary of the Rhone, about 60 km to the west of Valence.

Choirs, sports teams and official delegations from both municipalities visited the respective twin town.

After more than 40 years of partnership, it only stays alive, the union was confirmed and renewed since 1963 first in 5/30/2003 in Le Cheylard and in 5/21/2004 in Weilmünster with big participation of the population in attractive ceremonies.

The official local committees can support and promote, but the partnership remains vividly only if many citizens are interested in our twin town in future.

[7] Weilmünster lies on Bundesstraße 456 on which Weilburg and Bad Homburg vor der Höhe can be reached.

Since then, all the tracks have been torn up without a trace, and the railway's right-of-way has in great parts been used to build the Weil Valley Bicycle Path.

Within the framework of the reactivation of the Grävenwiesbach-Brandoberndorf railway line, a new connection to the rail network was considered for Weilmünster; however, there was no concrete followup to these plans.

There are a roadbuilding company, a furniture shop and a great number of small businesses and handicraft enterprises.

Weilmünster's main centre supplies medical, shopping and school services, and it is also there that the community nursing station and the local history parlour can be found.

Moreover, sporting events such as the Weiltal-Marathon in April, and the autofreie Weiltal (“carfree Weil valley”, held on a Sunday in August) keep drawing visitors to the community, as is also the case with the Weiltalweg and the new recreational vehicle campsite.
