Deriving from Truong Son Mountain, the two springs Ta Trach (Left Tributary) and Huu Trach (Right Tributary) meet at the junction of Bang Lang fork and create the Perfume River.
From Bang Lang to Thuan An estuary, the Perfume River is 30km long (The river level is not much above that of the sea) so that the river runs very slowly. The colour of the Perfume River is darker when it runs along the foot of Ngoc Tran Mount – the Jade Cup Temple (Dien Hon Chen) – where there is a very deep abyss.
The Perfume River is beautiful sight from its source, and runs among mountains, forest trees, plants, etc, bringing with it fragrances of tropical flora. The river runs slowly through the verdant and shady villages of Kim Long, Nguyet Bieu, Vy Da, Dong Ba, Gia Hoi, Dinh market, Nam Pho, Bao Vinh, mingling with the odors of flowers of Hue… The river with the shimmer blue limpid colour is like a pearl in the sun. Boats are rowed up and down with remote, meditative and deep folk melodies at deep night. It is an eternal pleasure for many generations of tourists who go boating to behold the poetic landscape, to listen to the folk melodies of Hue in tranquil nights.
The views on both sides of the river with the citadel, town, gardens, pagodas, towers and temples, etc. and their reflections in the waters make the already loveable river even more poetic and musical. Many people think that Hue city has peaceful, gentle and tranquil landscapes mostly thanks to the Perfume River. This river brings to the city a meditative poetic characteristics and the harmonious limpidity exhaling from a land of age-old culture.
Together with the Perfume River, 105m Ngu Binh Mount is the second invaluable gift endowed by Nature to Hue. These two mingle with each other creating the Romantic Mountain and river beauty of Hue. For a long time, this beautiful mount and the blue limpid Perfume River have become the symbol of Hue city. Therefore, people often call Hue “The land of the Perfume River (Huong River) and Ngu Binh Mount” or “Huong-Ngu Land”.
