The book in your hands is a tool to bring nature and the mountain to the younger group. It is a collection of thirty-four itineraries of varying difficulty for the Catalan Pyrenees, from Cap de Creus to the Aran Valley, and from Canigó to the Montrebei gorge. The selection of routes has been made under the prism of offering a good variety of itineraries that are a sample of the natural environment of the Pyrenean mountain range. I have also been careful to make proposals for all ages. I have also included, at the end of this volume, a series of itineraries that go beyond a simple walking tour and proposes a taste of other sports such as mountain biking, via ferrata and skiing. the bottom or the ascent with snowshoes. A tasting that allows us to begin to see all mountain sports, always with a principle of respect for the environment.
