Parque Nacional de Ordesa y Monte Perdido is Spain's oldest national park, established in 1918 to protect the stunning landscapes and biodiversity of the Spanish Pyrenees. The park spans 15,608 hectares and includes Europe's highest limestone wall, Monte Perdido (3,355 meters).
The park features dramatic limestone cliffs, deep canyons, and lush green valleys. Its most famous feature is the Ordesa Canyon, carved by the Arazas River over millions of years. The park's highest peak, Monte Perdido, is part of the Three Sisters massif, which also includes Monte Cilindro and Monte Tempestades.
The park is home to rare species like the Pyrenean desman, a small aquatic mammal, and the griffon vulture. It also protects endangered plants such as the Pyrenean endemic Saxifraga perdida. The park's strict conservation measures ensure minimal human impact, preserving its natural beauty.
The park offers numerous hiking trails, ranging from easy walks to challenging treks. The most popular route is the 12-kilometer round-trip hike to the Cola de Caballo waterfall, which takes about 4 hours. For experienced hikers, the ascent to Monte Perdido is a rewarding challenge, offering breathtaking views of the surrounding field.
Access to the park is limited to protect its fragile ecosystems. Visitors must park in designated areas and walk to the park entrance. Guided tours are available, providing insights into the park's geology, flora, and fauna. The park is open year-round, but winter access may be restricted due to snow.
