Hue, Vietnam: the citadel, the tombs and the rain

Hue: the Nguyen capital, the river and the rain

Short answer

Hue was Vietnam's capital from 1802 to 1945 under the Nguyen dynasty, and the Complex of Hue Monuments was inscribed by UNESCO in 1993. The Perfume River runs through the centre with the citadel on one bank. It is wet: about 3,200 mm a year, around 70 per cent of it from September to December.

A capital, not a monument

For 143 years this was where Vietnam was governed from. The Nguyen emperors held court inside a walled citadel on the north bank of the Perfume River, with a second wall inside it around the Forbidden Purple City, which was the private residence of the emperor and the people who served him.

A yellow tiled gate of the Hue citadel in heavy rain, puddles across the stone forecourt — The citadel in the weather it gets from September to December.

That is why the scale feels different from other sites in the country. You are not looking at a temple complex that grew. You are looking at a working seat of government that was laid out on purpose, with the ceremonial approach, the mandarins’ courtyards and the household quarters in the order the court needed them.

The war took a great deal of it. The Forbidden Purple City in particular is mostly foundations and fragments, and restoration has been running for decades. Knowing that before you walk in turns the gaps from a disappointment into part of the history.

The tombs are the other half

The Nguyen emperors built their tombs upriver, and they are not small. Each one is a compound with courtyards, pavilions, a stele, a lake and a burial enclosure, built to a different taste depending on the emperor who commissioned it.

They are spread along the Perfume River south and west of the city, so seeing several means a boat, a car or a motorbike and most of a day. Picking two or three and giving them time beats collecting all of them.

The rain is a planning fact

About 3,200 mm falls on Hue in a year, and roughly 70 per cent of that between September and December. This is the central coast pattern, which runs on its own calendar: dry when the north is wet, wet when the rest of the country is drying out.

That trips people up because Da Nang is an hour and a half away over the pass and the beaches there feel like a different climate. The month by month picture for all three regions is in when to go to Vietnam.

Arriving

Hue is on the main north to south line, and the ride from Da Nang along the coast and over the pass is the reason to take the train rather than the road. That route and how to book it are in the Reunification Express. Sleeper coaches run the same corridor, covered in sleeper buses in Vietnam.

Most people arrive from Hoi An, which is a half day away by road. Keep your phone working for the tomb runs and the weather, since plans here change with the sky: sizing is in how much mobile data for Vietnam and the plans are in the Vietnam eSIM store.

Questions

Why does Hue matter?

It was the capital of a unified Vietnam from 1802 to 1945, the seat of the Nguyen dynasty, and the court that ran the country from here left the citadel, the palaces and the imperial tombs behind. The Complex of Hue Monuments has been a UNESCO World Heritage site since 1993.

What is actually left to see?

The walled Imperial City with its gates and palaces, the Forbidden Purple City inside it, the Nguyen emperors' tombs spread along the river outside town, and Thien Mu Pagoda on the north bank. Parts of the complex were damaged in the war and restoration is ongoing, which is visible as you walk.

When does it rain?

Hue takes about 3,200 mm of rain a year and roughly 70 per cent of it falls between September and December. That is a different calendar from the beaches an hour away, so a dry week in Da Nang is not a promise of a dry week here.

How long is enough?

Two nights covers the citadel on one day and the tombs on another without rushing either. One night works if you accept that you are choosing between them. The tombs are spread out along the river, so the travel between them is part of the time.

How do I get there?

Hue sits on the main north to south railway, which is the pleasant way in, and the road from Da Nang crosses the Hai Van Pass. Buses and flights both serve the city. Coming from Hoi An it is a half day by road either way.
