Visitors are asked to follow the network of trails (art. 3 of the Park regulation). The itineraries are marked by official yellow signs with black writings of Regione Autonoma Valle d'Aosta. At the panoramic points there are illustrated panels providing topographical and naturalistic information (reading panels of the landscape and panels "Life-Natura").
Moreover, numerous small explanation placards are displayed along the three guided itineraries, for which specific illustrated brochures can be bought in the Park Offices.
