When people think of Hue, the majestic Perfume River always comes to mind. However, hidden deep within the mossy walls of the Hue Imperial City lies another waterway with a fascinating history: the Ngu Ha River, also known as the “King’s River.”
As a semi-artificial river with a unique L-shaped design, Ngu Ha is not just a relic; it is a peaceful escape perfect for travelers who love exploring Hue by bicycle.
1. The Royal History of Ngu Ha River
Ngu Ha was developed in two major phases during the Nguyen Dynasty to transport goods and regulate water within the Citadel:
1805 (King Gia Long’s Reign): The first section was dug, connecting the Dong Ba River to the Royal Arsenal (Vo Kho) and granaries. It was initially named Thanh Cau.
1825 (King Minh Mang’s Reign): The river was extended to the Ke Van River, completing a 3,700-meter waterway that bisects the Imperial City into Northern and Southern halves. It was then officially renamed Ngu Ha.
2. A Masterpiece of Royal Engineering
Flowing from the Tay Thanh Thuy Quan (Western Water Gate) to the Dong Thanh Thuy Quan (Eastern Water Gate), Ngu Ha River served as the “lungs” of the Citadel. It effectively regulated water levels to prevent flooding during Hue’s heavy rainy seasons.
Along its 3.7km length, the river is crossed by several historic bridges and culverts, each with its own story:
Vinh Loi Bridge
Khanh Ninh Bridge
Son Bridge (Cau Son)
Hàm Tế Bridge
3. Why Ngu Ha is a Must-Visit for Cyclists
For those renting a bike from Hue Smile Travel, the banks of Ngu Ha offer one of the most authentic “Local Hue” experiences. Unlike the busy tourist spots, Ngu Ha is lined with quiet residential neighborhoods, ancient garden houses, and local markets.
Scenic Ride: The path along Ngu Ha is flat and shaded, making it ideal for our Asama City Bikes or Fiido E-bikes.
Cultural Insight: You will see locals fishing, elderly people playing chess under the trees, and the slow pace of life that defines Hue.
Heritage Preservation: Since 2000, Ngu Ha has been protected as a Grade I Heritage Site. Recent restoration projects have cleared the banks and dredged the riverbed, bringing back its poetic beauty.

FAQ
Is the Ngu Ha River natural or man-made?
It is semi-artificial. Parts were dug anew under the king’s orders, while others were modified from existing small streams to form a continuous L-shaped waterway.
Can I take a boat on the Ngu Ha River?
Currently, the river is primarily for sightseeing from the banks. It is not a commercial boat route like the Perfume River, which makes it much quieter and better for cycling.
Is there an entrance fee to see the river?
No, the Ngu Ha River flows through public residential areas within the Citadel. It is free for everyone to explore.
