The surroundings of the Pollós River allow you to enjoy corners of great beauty, with waterfalls and cascades. Many trails start in the area of the Comapedrosa Natural Park, one of the most wonderful protected spaces in Andorra. You will traverse red pine forests, deciduous woodlands, and other tree species such as the elderberry, common hackberry, gatsaule, and trembling aspen. We will observe species like the spotted flycatcher, the white-rumped swallow, and the great and blue tits. In the Pollós River, there are also water pipits and the Pyrenean newt, as well as roes, foxes, martens, and badgers.
