The park is home to the last native populations of brown bears in the French Pyrenees.
The Cirque de Gavarnie features the highest waterfall in mainland France.
The park contains over 200 alpine lakes, formed primarily by glacial erosion.
The core area of the park is permanently closed to mountain biking and drone usage to protect nesting raptors.
The Pic du Midi d'Ossau is an ancient volcanic neck that remained after the softer surrounding rock eroded.
Pyrenean chamois, or 'isards', are the most populous large mammals in the park, with over 10,000 individuals recorded.
It is one of the few places in Western Europe with significant populations of marmots, which were reintroduced in the 1960s.
The park's altitude range covers four distinct bioclimatic floors: collinean, montane, subalpine, and alpine.
Parc national des Pyrénées stretches 100 kilometers along the Franco-Spanish border, covering over 45,000 hectares of high-altitude terrain. It is the only French national park that shares a border with another country, directly adjacent to the Spanish Parque Nacional de Ordesa y Monte Perdido. The park protects the Pic du Midi d'Ossau, a distinctive volcanic rock formation that serves as a landmark for the region. The core zone maintains a strict altitude range reaching 3,298 meters at the summit of Vignemale. Flora includes over 2,500 species, such as the endemic Ramonda myconi, and the park serves as a reintroduction site for the bearded vulture and the Pyrenean ibex. It incorporates the Cirque de Gavarnie, a UNESCO World Heritage site known for its 422-meter waterfall. The park administration manages six distinct geographical valleys: Aspe, Ossau, Azun, Cauterets, Luz-Saint-Sauveur, and Aure. No roads traverse the park's heart, ensuring it remains accessible only by foot or mountain trail.

Carry topographical maps, as mobile signal is non-existent in many deep valley areas.
Start hikes at dawn to avoid the most intense UV radiation and afternoon convective thunderstorms.
Always check local 'bulletin neige' (snow reports) before ascending above 2,000 meters, even in early summer.
Do not attempt high-altitude mountain passes without proper navigational equipment and physical preparation.
High-altitude trails and mountain passes are frequently blocked by snow until late June; some mountain huts close by late September.
No dogs allowed in the core zone, even on a leash. Camping is strictly prohibited except for bivouacking near refuges at sunset.
