In short
Gilded temples, colonial houses, monks at dawn and two rivers meeting. Luang Prabang is small and covered entirely on foot.
The Chinese high-speed railway brought it closer to the border and the capital, which changed the access without changing the atmosphere.
What it really costs
Very cheap on housing and food. The budget rises on the excursions: waterfalls, caves, Mekong cruises.
ATMs charge a high fee per withdrawal, and cash is still king.
When to go
November to February, dry and cool in the morning. March and April are marked by agricultural burning: the smoke cuts visibility and irritates the airways for weeks.
The monsoon, June to September, makes some tracks impassable.
What nobody tells you
The alms ceremony for the monks is a religious rite, not a show. It is watched from a distance and in silence.
Internet coverage is decent in town and non-existent the moment you leave it. This is not a base for demanding work.
