Heritage is a very broad concept as it has been expanded since its inception at different typological, chronological and geographical levels. It encompasses several formations ranging from an isolated object to a delimited site which have been recognized for their exceptional, universal values and their scientific, historical, aesthetic characteristics, etc. Classified heritage can be cultural or natural. Protected natural areas (PNAs) belong to the natural heritage. They are defined as terrestrial and/or marine areas that are delimited in order to ensure better protection against external factors that could disturb or interfere with the biodiversity they contain. Due to their intrinsic qualities, these protected natural areas require protection and tourism development measures.
