The Perfume River has two sources; both begin in the Dãy Tr??ng S?n mountain range and meet at B?ng Lãng Fork. The T? Tr?ch (left tributary) originates in the Tr??ng ??ng mountains and flows northwest towards the fork. The river then flows in south-north direction past the temples of Hòn Chén and Ng?c Tr?n, then flows north-west, meandering through the Nguy?t Bi?u and Luong Quan plains. Continuing on, the Sông H??ng (H??ng River) flows to the northeast to Hu? and passes the resting place of the Nguy?n emperors. The river continues, passing Hen islet and various villages, crossing the Sinh junction (capital of ancient Châu Hóa) before emptying into the Tam Giang lagoon.
