Here is a list with some itineraries of intermediate difficulty: we are not including very short walks or hikes dedicated only to expert and trained hikers (you can find in this case a complete bibliography).
The Park thematic trails tell the tourist, through a series of settings, the naturalistic, environmental, cultural and historical aspects of some places and itineraries in the protected area. They tell the rich biodiversity and allow the tourist to read and discover the different aspects of the territory.
