Nong Khai is a long thin province running along the Mekong River, providing the main access to Laos. Originally people went by boat from Tha Sadet, but the building of the Friendship Bridge across the Mekong has made Nong Khai a major centre for transport and trade with Laos.

Attractions include Wat Pho Chai, renowned for its large seated Buddha believed to have been cast in Lan Chang, and Phra That Nong Khai, an old chedi that slipped into the river and can now only be seen completely in the dry season.

Sala Kaeo Ku is a bizarre sculpture garden packed with statres of Shiva, Vishnu and Buddha as well as many other figures from Hindu and Thai culture. Phu Wua Wildlife Sanctuary near the Mekong River contains a number of beautiful waterfalls.

Nong Khai is 615 kilometres from Bangkok and has an area of 7,739 square kilometres. It consists of the following districts: Mueang Nong Khai, Bueng Kan, Phon Phisai, Tha Bo, Sangkhom, Seka, So Phisai, Si Chiang Mai, Phon Charoen, Pak Khat, Bueng Khong Long, Si Wilai, Bung Khla, Sa Khrai, Rattana Wapi, Fao Rai and Pho Tak.
