Emblematic because of its perfect cone shape, Puy de Pariou attracts more than 100000 visitors a year. Its physical integrity should be ensured by limiting erosive risks through appropriate arrangements that take into account the quality of reception, the preservation of soils and respect for the environment. The main aim is to improve the access path to the summit by slightly altering its route, to heal the departure of old paths, to strengthen the path of the lip of the crater by paving stone on the most fragile sections, to resume the descent entirely into the crater, to treat the foot of the staircase, and to improve the path of Fontmagnie at the foot of the Pariou.
