Created in 1943, the Orlu Reserve (4250 ha) became a national wildlife reserve in 1998, due to its heritage interest. The French Biodiversity Office ensures its management there and develops programs for the study and monitoring of wildlife.

The French Office for Biodiversity (OFB) ensures its management and develops programs for the study and monitoring of wildlife. The OFB works in partnership with a local structure, the Mountain Observatory, to carry out study, monitoring and promotion programmes.

- Study and monitor the evolution of wildlife and its habitats: OFB agents regularly monitor biodiversity, particularly sensitive species. Endemic to the Pyrenees, the izard and the capercaillie hold a special place there. The in-depth studies of which they are the subject contribute to a better understanding of these two species and their management.
- Sustainably preserve the fauna and flora: The environmental awareness and policing actions carried out by OFB agents for the benefit of the natural heritage are based on the results of field studies. By respecting the instructions on the boundary markers of this territory and its discovery trail, you will discover a remarkable biodiversity while contributing to its conservation.
- Raising awareness of adults and children: The Mountain Observatory has created several tools for discovery and awareness of the natural heritage of the Orlu National Reserve:

The “Maison de la Réserve” in the hall of the Observatory is made up of interactive terminals with free access. It is an essential space for consulting hiking maps, the weather forecast, scientific data on the reserve... All year round, discovery outings are supervised by specialists.

Due to its shared management recognized as exemplary, the Orlu Reserve was included in the Green List of the IUCN (International Union for Conservation of Nature) in 2019.

Enjoy a preserved natural Eden ...
Admire the chamois that roam the steep slopes of the National Reserve of Orlu, listen to the marmots whistle... Look up, in the sky soar the great griffon vultures and the kestrels.

A one-hour walk will take you to the heart of the reserve among the marmots, while three hours will take you to the En Beys refuge. More committed routes will allow experienced mountaineers to reach crests and summits. See section "to see, to do, walks and hikes"
