Bắc Ninh

Bắc Ninh lies conveniently less than an hour northeast of Hanoi, and so is well within commutable distance from the capital. With a sizeable population, it has a rich Buddhist heritage and is famous for Quan Họ folk singing. It boasts the Đền Đô Temple and its accompanying colourful annual procession, along with cleaner, better air quality and an opportunity to experience fairly smog-free lungs.

Population: 1.131 million
