Parc nacional d'Aiguestortes, officially Aigüestortes i Estany de Sant Maurici National Park, spreads above the village of Boi in the Catalan Pyrenees, where water, rock and pine forest share the same steep amphitheatre. Declared a Spanish national park in 1955, it remains the only national park in Catalonia and centres on a high plateau cut by twisting mountain streams and glacial lakes.
Where water shapes the mountains
The name Aiguestortes refers to the “twisted waters” that mark this landscape: high mountain streams that bend and loop across open meadows before dropping into rocky gullies. More than 200 glacial lakes, or estanys, lie in hollows carved by ice, their surfaces framed by granite peaks and ridges.More than 200 lakes and extensive wet meadows make water the most visible feature of the park throughout its high valleys.
The protected area stands in the central Pyrenees of Spain’s Lleida province, with the strict national park zone covering 14,119 hectares and a wider peripheral protection belt around it.The official figures for the park and its buffer zone underline how far the watersheds, peaks and forests extend beyond the core valleys seen on many postcards.
Granite peaks, high plateaus and the Encantats
Parc nacional d'Aiguestortes occupies a block of high mountain terrain divided between the Alta Ribagorça, Pallars Sobirà, Pallars Jussà and Val d'Aran counties of Catalonia.The guide to visiting the park describes a mosaic of ridges, cirques and hanging valleys shaped by glaciers and dominated by pale granite.
Among the peaks, the jagged twin summit known as Els Encantats rises above Estany de Sant Maurici and has become one of the most recognisable outlines in the Catalan Pyrenees.Official park publications highlight Els Encantats and the lakes as emblematic features of the protected area. Away from this celebrated skyline, the terrain alternates between broad U-shaped valleys, stepped plateaus filled with bogs and streams, and steeper sections where paths wind through pine and fir forest.
From Boi and Espot into the high valleys
The national park was created on 21 October 1955 under a Spanish decree, becoming the second national park in the Pyrenees after Ordesa and Monte Perdido.Its legal creation in 1955 fixed the protection of the upper valleys around Aiguestortes and Estany de Sant Maurici. Subsequent extensions enlarged the protected surface and linked the core zones through a single management framework.
Access into the central valleys follows historic routes from both sides of the range. On the western side, paths and transport services climb from the Vall de Boí in Alta Ribagorça, reaching the high pastures and streams above Boi, while on the eastern side approaches from Espot in Pallars Sobirà lead towards Estany de Sant Maurici and the foot of Els Encantats.Visitor information from Catalonia’s tourism authorities highlights these twin gateways and the role of the surrounding valleys in supporting the protected area through accommodation, local transport and information centres.
