Welcome to Parque Nacional de Ordesa y Monte Perdido
This is where the Spanish Pyrenees really take your breath away. The park extends south from a dragon's back of limestone peaks along the French border: a southeastward spur from this includes Monte Perdido (3355m), the third-highest peak in the Pyrenees. Deep valleys slice down from the high ground. Most were carved by glaciers and at their heads lie bowl-like glacial circos (cirques) backed by spectacular curtain walls of rock. Chief among the valleys are Ordesa (west), Añisclo (south), Escuaín (southeast) and Pineta (east).
The wonderful scenery of plunging canyons, towering cliffs, thick forests, rivers, waterfalls, snow peaks, mountain lakes and high-level glaciers makes this arguably the place to head for if you can manage only one destination in the Spanish Pyrenees.
