Parc nacional d'Aiguestortes and its winding waters
Published on 09/23/2026 at 13:19 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Parc nacional d'Aiguestortes lies in the central Pyrenees of Catalonia, above the Vall de Boí in north-eastern Spain. Its visible signature is water: high mountain lakes, streams and broad meanders winding through alpine valleys.
Granite valleys shaped by water and ice
The park contains close to 200 lakes, known locally as estanys, together with streams, waterfalls and wetlands. Many occupy hollows associated with glacial landscapes, where granite peaks surround dark or vividly coloured water.
The name Aigüestortes refers to the park’s winding mountain waters. In the Aigüestortes sector, broad bends cross the high valley floor, while the Sant Maurici sector contains the lake named in the park’s full title. Peaks and ridges frame both landscapes.
From a 1955 national park to a protected Pyrenean landscape
Parc nacional d'Aiguestortes was created by decree on 21 October 1955. Its original protected area covered 9,851 hectares, and the park became Spain’s fifth national park.
The protected park area reached 14,119 hectares after an extension in 1996. A surrounding protection area brings the wider protected landscape to more than 40,000 hectares. The park remains Catalonia’s national park and lies across the high valleys of Alta Ribagorça and Pallars Sobirà.
Boí, Romanesque churches and mountain routes
Boí is the principal gateway to the Aigüestortes sector. The village stands in the Vall de Boí, a valley also known for its Romanesque churches, including Sant Joan de Boí, Sant Climent de Taüll and Santa Maria de Taüll.
The churches form the Romanesque heritage of Boí, inscribed as a UNESCO World Heritage ensemble on 30 November 2000. Mountain paths connect valleys, lakes and viewpoints, with terrain ranging from forested slopes to exposed high-mountain ground.
The park’s two principal sectors give it a distinctive visual contrast. Aigüestortes presents meandering water across open valley floors, while Sant Maurici places a mountain lake beneath the twin rock towers of Els Encantats.
