Aghione is located in Upper Corsica, at an altitude of 62 metres and is part of the ancient parish of Aléria. This small village is crossed by the Tagnone – a tributary of the Tavignano, the second longest river of Corsica – which divides the commune into a hilly area to the north and a plain area to the south. Aghione does not have a direct access to the sea, which is at 5 km from the village.

Here, agriculture and breeding are still common and remain important activities for the economy of the region: the hills are used for pasturing pigs, goats and sheep, while the plains are rich in fruit trees and grapevines.
If you want to visit Aghione, you should know that there are no shops in the village, which is very vast. In fact, the chief town has just few private houses; the town hall is located in the hamlet of Casone, on the plain to the north-west; and the hamlet of Chioso has many private houses.

In the village you can visit the church of St Filippo, which is in good condition because was renovated in 2012. This small church is separated from the public road by the municipal cemetery. On both sides of the Tagnone you can see an old thermal establishment, which is now completely abandoned.

Aghione was the birthplace of François Antoine Bonelli (1827-1907), one of the most famous Corsican bandits, who was also mentioned by the writer Guy de Maupassant.
The village is crossed by the departmental road 343 and is located at about 51 km from Corte.
