This protected park in the parish of Ordino runs along both banks of the Sorteni River and covers an area of more than 1000 hectares. Despite being the smallest of the three, it is rich in biodiversity, with over 700 species of flowers and plants. Most of the park is dedicated to educational purposes. It has its own botanical garden with species known only in the Pyrenees and native to this natural park, and has accessible routes for all levels. The park's wildlife includes the ibex, Pyrenean river salamander and common frog. The Center de Natura, a modern interpretation and exhibition center of the park, is located in the village of Cortinada. There is also an information booth in the main car park, open in summer, near the village of Serrat. There are many hotels just 10 km from Ordino, as it is located close to the Ordino Arcalis ski resort.
