The Mosquera valley, in the heart of the Sierra de Espadán Natural Park, is known for being a true natural treasure, one of the best preserved and most renowned spaces in the Park. However, since the mid-19th century, this space has been profoundly altered by people making commercial use of the forest. Paradoxically, it is precisely this anthropic transformation that makes the place more ... [Show full abstract] attractive to visitors, to the extent that it continues to be a leading destination for nature observation and outdoor sports. Since the area was designated as a natural park, visitor numbers have increased exponentially, whilst its use as a managed forest has gone into decline. Both situations pose a challenge for the maintenance and preservation of this mountain area. The aim of this research is to present the strong symbolic component of the Mosquera valley and to evaluate the new uses of this privileged space, the new forms of tourism, the rise of sports practice, the enhancement of heritage or the improvement of behaviour in favour of sustainability.
