The park hosts the solar furnace of Odeillo, one of the largest in the world, utilized for high-temperature research.
It contains the highest railway station in France, Bolquère-Eyne, located at an elevation of 1,593 meters.
The park is home to the only habitat of the endangered Pyrenean desman in the eastern part of the mountain range.
Over 100 glacial lakes are situated within the park boundaries, mostly concentrated around the Carlit massif.
The regional park is part of the Parc naturel régional network, which prioritizes the preservation of rural heritage alongside environmental conservation.
The Regional Park of the Catalan Pyrenees spans 138,000 hectares across the Pyrénées-Orientales department, bridging Mediterranean and high-altitude mountain ecosystems. It serves as a protected zone for biodiversity, including the endangered Pyrenean desman and the bearded vulture. The territory features a diverse geological landscape ranging from the Têt valley floor to peaks exceeding 2,900 meters such as Pic Carlit. Natural thermal springs, specifically in Llo and Saint-Thomas-les-Bains, are a primary feature resulting from localized tectonic activity. The park integrates 64 distinct communes, maintaining traditional agricultural practices like transhumance. Hiking trails within the park provide access to glacial lakes, including the Bouillouses lake complex. It is a certified Dark Sky Reserve, offering low light pollution for astronomical observation. Cultural sites include the UNESCO-listed Vauban fortifications in Mont-Louis and Villefranche-de-Conflent located within its borders.

Pack layers for rapidly changing weather conditions, as temperatures can drop significantly as you gain altitude.
Check for fire restrictions or trail closures during dry summer months before planning long-distance hikes.
Use dedicated park-and-ride shuttles during peak summer weeks to access popular sites like Lac des Bouillouses.
Attempting high-altitude summits without proper mountaineering gear or during unforecasted weather shifts.
Access to certain high-altitude roads is restricted to shuttle buses during peak summer months; some mountain passes are closed by snow during winter.
Stay on marked trails to protect fragile alpine flora; adhere strictly to 'Leave No Trace' principles; keep dogs on a leash in protected zones.
