The borders drawn by Vespasian ran west of the River Indus (which flowed from its upper valley in Caria) from the Pisidian plateau up to Lake Ascanius (Burdur Gölü), to the south of Apamea.

In the north and east it formed a line which followed the shores of the lakes Limna (Hoyran Gölü) and Caralis (Beyşehir Gölü), turned south towards the Gulf of Adalla (mare Pamphylium) and followed the Taurus Mountains (Toros Dağları) for some ten miles towards east up to Isauria.

Important cities were Side, Ptolemais, Gagae and Myra on the coast, Seleucia, inland and Cremna, Colbhasa and Comama, on the Pisidian Plateau, where Augustus had founded Roman colonies (settlements).

Other important cities in Lycia include Pednelissus, Ariassus, and Sagalassus; along the Eurymedon, Aspendus and Perge, which had a sanctuary of Artemis.

Lycia and Pamphylia were under of Diocese of Asia (Dioecesis Asiana), of the Praetorian Prefecture of Oriens (the East).
