- Frame: The Mediterranean lies to the east, the Corbières to the north and the Pyrenees and Albères to the west and south.
- Rivers: The Agly, Têt and Tech valleys help organise the inland landscape.
- Coast: The Côte Vermeille runs south of the plain towards Spain, where steep vineyard slopes meet the sea.
