Description

Context The circular trekking route through the Natural Park of Posets-Maladeta in the Aragonese Pyrenees spans approximately 50 km with over 4,300 meters of cumulative elevation gain. This protected area hosts some of the highest peaks in the Pyrenees, including Posets (3,375 m) and Aneto (3,404 m), and features a rich mix of red pine forests, alpine meadows, and glacial ibones. The wind carries the scent of thyme and resin as you walk along trails that connect three major valleys.

The Experience Over five days, you’ll travel between iconic mountain refuges such as Ángel Orús, Estós, and Biadós, crossing diverse landscapes—from the cool shade of the woods to the rugged, icy textures of high-altitude terrain. An optional ascent to the summit of Posets offers panoramic 360° views of the Aneto-Maladeta massif, while the call of the capercaillie echoes at dawn. The journey balances physical effort with quiet moments to absorb the serenity and purity of the alpine environment.

For Whom This route is suitable for hikers with medium to high experience and strong physical endurance, aged 14 and older. It is not recommended for beginners, those with limited fitness, or travelers seeking short trails or routes without overnight stays in mountain huts.

Local Context The refuges visited are part of the Pyrenean mountain tradition, where shepherds and mountaineers have long lived in harmony with wild nature. The region preserves ancestral practices such as transhumance, and local wildlife like marmots and rock ptarmigans reflect the balanced alpine ecosystem.
