The lake takes its name from the historic 'Old Forges' that once operated in the valley, reflecting the region's industrial heritage.
The reservoir's water levels are regulated to support regional hydrological management while maintaining recreational accessibility.
The forest surrounding the lake is part of a larger contiguous woodland area that remains one of the least fragmented in France.
The site hosts a diverse range of amphibians and dragonflies due to the specific acidity and quality of the freshwater environment.
Lac des Vieilles Forges is a 150-hectare artificial lake situated in the heart of the Ardennes Regional Nature Park. The reservoir was created in 1927 by the construction of a dam on the Faux stream to provide energy for local metallurgical industries. It is currently managed as a leisure base offering swimming, canoeing, and pedal boat rentals. The surrounding landscape consists of dense coniferous and deciduous forests typical of the Massif des Ardennes. A marked trail system encircles the lake, spanning approximately 12 kilometers in length. It functions as a protected natural site for migratory birds and local wildlife populations. The shoreline includes sandy beaches designated for public bathing during the warmer months.

Bring insect repellent, as the forested lakeside environment attracts mosquitoes and gnats.
Use the dedicated gravel parking areas rather than parking on the grass to avoid fines.
Check local weather forecasts specifically for the Ardennes region, as mountain-like microclimates can cause sudden temperature drops.
Attempting to swim outside of designated, lifeguard-monitored beach zones during peak summer months.
Supervised swimming areas are seasonal, typically operating only during the summer months.
Respect noise levels near nesting bird zones; swimming is permitted only in designated supervised beach areas.
