Hills to the northwest are included in the national park; the village of Ospedale there probably takes its name and origin from a large ancient hospital of the Roman era. It never lost that function but continues as a health center employing about 150 people. Nearby is a reservoir, the Lac de l'Ospedale, created with a dam at the foot of punta di Corbu in the forest of Ospedale. These hills culminate at the "peak of the dead cow" (punta di a Vacca Morta).
