Nong Khai Province Guide: History, Towns and Local Products
Nong Khai lives along the Mekong. Across the water lies Laos, and a short drive upstream the Thai-Lao Friendship Bridge, the first bridge over the lower Mekong, carries traffic and trains towards Vientiane.
This guide looks at the river's role in the province's story, from border town to Sala Keoku's concrete giants, visits its districts and lists the rice paper and river foods its markets sell.

Why Nong Khai looks across the river
For most of its history Nong Khai faced the Lao towns on the opposite bank more than it faced Bangkok. That link was made concrete in 1994, when the Friendship Bridge opened between Nong Khai and the Vientiane side; in 2009 a railway line began running across it to Thanaleng in Laos.
The river also shapes the province's legends. Every October, at the end of Buddhist Lent, crowds gather at Phon Phisai to watch the Naga fireballs, glowing balls said to rise out of the Mekong. In town, the sculptor Bunleua Sulilat began Sala Keoku in 1978, a park of giant concrete Buddhas, nagas and Hindu deities. In 2011 the eastern districts were split off to form Bueng Kan province.
