Aydius is located some 25 km south by south-east of Oloron-Sainte-Marie just east of Bedous. Access to the commune is by the D237 road from Bedous which goes to the village and terminates there. The commune is alpine in nature with extensive forests, rugged terrain and snow-capped mountains in the east.[5]
The Gabarret river rises in the east of the commune and flows west gathering a large number of tributaries including the Ruisseau d'Arces, the Ruisseau du Saslars, the Gave de Béranfueil, the Gave de Bouren, the Ruisseau d'Ilhiec, the Ruisseau Sarité, the Ruisseau de Traillère, and the Ruisseau de Sahun (which forms part of the western border of the commune) before flowing west to join the Gave d'Aspe at Bedous.
The commune name in Gascon is Aidius. Michel Grosclaude said that the name probably comes from the same root as Aydie but its origin and meaning remain obscure.[8]
The following table details the origins of the commune name and other names in the commune.
A rock shelter dating from prehistory called Abri Gandon-Lassus has been discovered in the commune.[12]
Paul Raymond noted on page 18 of his 1863 dictionary that the commune had a Lay Abbey, vassal of the Viscounts of Béarn and that in 1385 there were 30 fires and Aydius depended on the bailiwick of Aspe.[6]
The commune is part of four inter-communal structures:
the Communauté de communes du Haut Béarn;
the Energy association of Pyrénées-Atlantiques;
the inter-communal association for aid to education in the Vallée d'Aspe;
the joint association for Haut-Béarn.

In his book L'ours et les brebis (The Bear and the sheep), Etienne Lamazou recounted his life as a transhumant shepherd from 1913 to 1969. Originally from Aydius, he never left except to take his cattle to their winter plain. He recounted the life of a shepherd as it still existed at the beginning of the 20th century. All the action takes place in and around Aydius and the book has many thousands of anecdotes sometimes soothing, sometimes moving, and often instructive.
