Overview of Ordesa y Monte Perdido National Park
Located in the Huesca Pyrenees within Spain’s Aragonese province, Ordesa y Monte Perdido National Park is a breathtaking natural sanctuary. Encompassing territories across the municipalities of Broto, Bielsa, Fanlo, Puértolas, Tella-Sin, and Torla-Ordesa, the park is a jewel of the Pyrenean landscape.
Its ecological and geological importance has earned it a series of prestigious protections. It became a UNESCO World Heritage Site in 1997, a Biosphere Reserve in 1977, and a Special Protection Area for Birds in 1988. Dominating its terrain is the Tres Sorores (Treserols) massif, the tallest limestone formation in Europe. It’s crowned by Monte Perdido, whose dramatic elevation gives rise to a network of glacial valleys and ridges.
The most iconic of these is the Ordesa Valley, which runs east to west and is carved by the Arazas River, the park’s lifeblood. Geologically, the park owes its dramatic topography to the alpine folding of the Tertiary period, later sculpted by Quaternary glaciation.
This combination of uplift and erosion has created well-defined glacial cirques, steep cliffs, and valleys like Ordesa and Pineta. Today, remnants of this icy past still cling to the northern face of Monte Perdido, though the glacier is gradually shrinking.
Wildlife in Ordesa y Monte Perdido National Park

Ordesa y Monte Perdido National Park is a thriving haven for wildlife. Among the park’s most iconic residents is the elusive brown bear, a top predator with a fragile population of around 40 individuals, making sightings rare and special. The rugged highlands are also home to the chamois, a nimble goat-antelope perfectly adapted to the steep terrain.
In lower altitudes and dense woodlands, wild boar, red deer, and the burrowing European badger roam freely, while red squirrels dart through the forest canopy. The alpine zones are alive with the whistles of alpine marmots while the waterways shelter the rare Pyrenean desman, a semi-aquatic mammal.
The skies are equally rich in life, with 171 bird species recorded, including several powerful raptors. Towering over the landscape, the golden eagle soars while the bearded vulture has also been sighted within the park. Alongside them glide the massive griffon vultures and the striking Egyptian vulture, the smallest of the park’s vulture species. Other birds include hawks, falcons, and songbirds.
Best Time to Visit Ordesa y Monte Perdido National Park
The best time to visit Ordesa y Monte Perdido National Park largely depends on what kind of experience you’re after. However, spring and summer generally offer the most favorable conditions. Spring (April to May) brings mild weather and a burst of color, as wildflowers blanket the meadows and waterfalls swell with snowmelt. This makes trails like the popular Cola de Caballo route very scenic.
Summer (June through August) is peak season for hikers.The window offers long daylight hours, warm temperatures, and full access to the park’s dramatic valleys and high-altitude trails. This is also the best time to enjoy the park’s iconic waterfalls at their most powerful. For a quieter but equally beautiful visit, autumn (September to November) reveals a different kind of magic.
The beech forests along the Ordesa Valley trail turn brilliant shades of gold and crimson, and the cooler temperatures are perfect for trekking without the summer crowds. Winter (December to March) transforms the park into a serene, snow-covered wilderness ideal for experienced adventurers. However, many trails may be inaccessible due to heavy snow cover.
Getting to Ordesa y Monte Perdido National Park
Reaching Ordesa y Monte Perdido from Madrid is straightforward. The most direct route is by car—a scenic but lengthy drive of around 7 to 8 hours. The journey takes you along major highways such as the A-23/E-7 and N-260 before arriving in the picturesque mountain town of Torla, the gateway to the park.
During busy periods like summer, Easter, and national holidays, private vehicle access to the Pradera de Ordesa—where most hikes begin—is limited. You’ll need to take a shuttle bus from the Torla Visitor Centre. For those opting for public transport, you can take a long-distance bus from Madrid to Huesca, the nearest major city to the park.
From there, local buses or taxis will get you to Torla, where regular shuttle buses continue to the Pradera. Alternatively, you can fly into Huesca-Pirineos or Zaragoza Airport. After landing, connecting buses or trains will take you to Huesca and onward to Torla.
Other Activities in Ordesa y Monte Perdido National Park
While Ordesa y Monte Perdido offers a wide range of experiences, hiking remains its most iconic draw. The Ordesa Valley has four exceptional day routes that begin at the Pradera car park and cater to every level of adventurer. The most popular option is the valley floor trail, a 16-kilometer round trip with moderate elevation gain. It’s perfect for those seeking a gentler day immersed in nature.
For a more challenging outing, try the Faja de Pelay route. The trail offers a dramatic ascent to a cliffside viewpoint before following a breathtaking ledge path along the southern wall. On this path, you’ll be treated to sweeping views of the 3,000-meter peaks and the legendary Brecha de Roland.
On the northern side of the valley, the Faja Racon trail provides a quieter, less-traveled experience beneath massive limestone walls. On this path, hikers are treated to the park’s geology and it also offers a good chance to spot sarrios or lammergeiers. The most daring hikers can take on the Faja de las Flores.
It’s a high-altitude, adrenaline-pumping route that climbs over 1,100 meters to a narrow ledge path etched into the cliff a kilometer above the valley floor. With exposed sections requiring passage over pitons and chains, it’s a test of nerves as much as stamina, but the panoramic views make the effort unforgettable.
