The reserve occupies the site of a massive former EDF lignite coal mine that ceased production in 1992.
Approximately 20,000 to 25,000 common cranes winter here annually, representing a significant portion of the western European migratory population.
The reclamation project involved reshaping the industrial landscape into a series of interconnected lakes and ponds.
The water levels in the central lake are strictly managed to provide safe roosting islands for birds, protected from terrestrial predators.
It is the only national hunting and wildlife reserve in the Landes department.
The site hosts a rare population of European pond turtles, a species threatened throughout its range.
The diverse habitat supports over 150 species of birds, including birds of prey like the marsh harrier.
Large sections of the reserve are strictly off-limits to the public to minimize disturbance to wildlife nesting sites.
The Arjuzanx National Hunting and Wildlife Reserve is a protected site located on a former open-cast lignite mine reclaimed as a wetland ecosystem. It serves as the primary wintering site in France for the common crane (Grus grus). The reserve spans over 2,600 hectares, featuring diverse habitats including lakes, marshlands, and pine forests. Its restoration project, initiated following the closure of the mining operations in 1992, has successfully created a sanctuary for endangered species. The site is managed to balance environmental preservation with public access through designated observation points. Water quality is maintained to support a high density of aquatic flora and fauna. The infrastructure includes a specialized visitor center providing educational resources on ecological succession. Birdwatching is the primary activity, with thousands of cranes arriving annually between November and February.

Bring high-quality binoculars or a spotting scope, as observation points are often set at a significant distance from the main roosting areas.
Follow the marked 'Sentier de la Mine' to understand the history of the site's ecological transition.
Check the visitor center for daily bird counts before heading to the observation hides.
Do not attempt to walk off-path, as the terrain includes unstable mining residue areas and protected sensitive habitats.
The visitor center operates seasonally; the reserve may have restricted access during peak breeding seasons or maintenance periods.
Maintain silence near observation hides, use camouflage clothing if possible, and strictly remain on designated trails to avoid disturbing nesting wildlife.
