El Parrizal - curso alto del río Matarraña - Bildbanksfoto

Mountainous landscape carved by the Mataraña river and the Ulldemó full of hiking trails and the possibility of climbing the rivers with bath included in the innumerable pools that are forming. Due to the porous terrain, the rivers sculpt the rock with great ease and form narrow and deep steps that in summer are dry and can be done on foot, although a good dip is also recommended.
