Hue is my favorite place to soak up late afternoon colors and enjoy an evening wandering the local streets, in all of Vietnam.
Hue is located in central Vietnam on the banks of the Perfume River, just a few miles inland from the South China Sea. The French colonial influence is ever present and makes for beautiful contrasts in architecture in the area around the south bank of the river. After a day of exploring the canals, the nearby tombs (Minh Mang's) and the citadel (the Imperial City), I'd encourage you to head toward the old historical district in the late afternoon.
The Mandarin Cafe on the south bank is a great spot for a cocktail and dinner, before heading back out for a few laps with your camera when the sun goes down. Once night falls, Hue's lantern shops set up shop, illuminating the alleys in striking colors from these paper stars.
