The Perfume River, or Song Huan River, is a river that crosses the city of Hue.
In the autumn, flowers from orchards upriver from Hue fall into the water, giving the river a perfume-like aroma, hence the sobriquet.
From Bang Lang to Thuan An estuary, the Perfume River is 30 km long and runs very slowly.
The Perfume River darkens as it winds along the foot of Ngoc Tran Mountain, home of the Jade Cup Temple, where there is a very deep abyss. Numerous songs and poems sing the praises of this river and of the colorful life on its banks. Yet Hue is not only the city at the river, Hue is in fact the cultural heart of Vietnam.
