“Water trekking” for sightseeing in legendary Hue
Ngu Ha is a man-made canal in the shape of a carpenter’s square. It flows through the Citadel and is linked with the “water quadrangle" by the two water gates: Tay Thanh Thuy Quan (Western Water Gate) and Dong Thanh Thuy Quan (Eastern Water Gate), forming a perfect system of water routes from outside to inside.
