Nong Khai (หนองคาย) is a city in Isaan. The city lies on the west bank of the Mekong River, 20 km from Vientiane, the capital of Laos. Known as the Naga City (Nagas being the giant serpent guardians said to inhabit the Mekong River - see below) and famed for its lovely position on the Mekong, Nong Khai is a bustling Thai town and the gateway to Laos and Vientiane. It has many beautiful features which attract a considerable number of Thai and foreign visitors every year, including Sala Keaw Khu the almost surreal sculpture park; the enormously revered Luang Por Phra Sai Buddha Image which has a remarkable history; the truly extraordinary Phu Phra Bat Historical Park (though in Udon Province it is easily reached from Nong Khai); and the Thai-Lao Indochina Market called Tha Sadet Market which occupies many streets in the centre of town. A large part of the centre of town, including the river bank, has been made pedestrian-only.

The Buddha image at Wat Po Chai is especially interesting. It is one of three Buddha images cast for the three daughters of King Setthathirath of Laos. The daughters were called Serm, Suk and Sai, and so the images are known as Phra Serm, Phra Suk and Phra Sai. Following wars between Thailand and Laos in 1827-28 to put down the aspirations of Chao Anouvong of Laos, the three images were taken from Vientiane by the Mekong River by the victorious Thais for eventual transportation to Bangkok. During a storm Phra Suk fell into the river, never to be recovered. Phra Serm was successfully removed to Bangkok, but on each attempt to transport Phra Sai to the Thai capital, some problem occurred and the image was left in Nong Khai, supposedly awaiting the re-emergence of Phra Suk from the Mekong. This valuable bronze and gold Buddha image is displayed on 13 April every year at Songkran.
The unexplained appearance of the famous Mekong Fireballs takes place on the last night of Buddhist Lent. They are visible from several points along the river bank but the most famous place to view them is Phon Phisai, 40 km east of Nong Khai. These mysterious pink, glowing balls arise silently from the river after dusk, and are visible on this night only. Also known as the Naga Fireballs (after the Mekong River Naga), they appear for only a few seconds before disappearing as mysteriously as they appeared. There are many theories as to the cause of these fireballs. Many locals believe it is better not to know and would rather enjoy the festivities instead. Sceptical Westerners visiting the event report they are more akin to fireworks emanating from the Laos riverbank, but generally keep their theories to themselves.
Famous for its giant catfish and displays various ocean-dwelling species as well as freshwater species. A good place to visit and relax, with a picnic garden area and a few drink stalls also available. On weekends the aquarium puts on scuba diving shows.
Sunken Chedi
A large Lao-style chedi that was submerged in the Mekong in the 18th century. The chedi eventually fell over into the river in 1847 and is marked by a number of flags in the middle of the Mekong, which can be seen in the dry season when the water level drops. It is also known as the Holy Reliquary in the Middle of the River, and was supposedly built to conserve Buddha's right foot. A replica of the chedi, called Phra That Klang Nam, was built in 2006 and sits on the banks of the Mekong nearby.
One of the most famous and beautiful attractions in Thailand. This historical park dates back more than 3,000 years and contains large and mysterious rock formations. Transport to Phu Phra Bat is available in the form of motorbike, car, or bus and can take a day to travel and experience it. It is also possible to stay overnight at Phu Phra Bat Historical Park, and this is highly recommended.
Phu Phra Bat was opened to the public in 1989 and is maintained by the Fine Arts Department of Thailand. Phu Phra Bat is known to be a very spiritual and peaceful environment and is a must-see for tourists, whether it be a day-trip or an overnight stay.
Sala Keoku or Wat Khaek
One sight that cannot be missed. This utterly bizarre park of massive sculptures (some over 20 m tall) is the handiwork of the mystic, Luang Pu Bunleua Sulilat, who bought the land in 1978 when he was kicked out of his native Laos. A similar park of his earlier work remains near Vientiane. Synthesizing Buddhism and Hindu ideologies, Buddhas, many-armed goddesses, naga snakes and all sorts of human-animal hybrids dominate the scenery.
Temple of the Table Mountain
It's a rocky outcrop jutting from the Mekong floodplain. It can be ascended by steps and ladders built by Ajarn Juan, a celebrated monk and visionary who was famed throughout Thailand. There are seven levels of wooden steps, ladders, roots and rocks on the mountain which represent the seven levels of spiritual enlightenment in Buddhist philosophy. Inside caves and sitting on cliffs, you will find many meditation huts that are used by monks from all over northeastern Thailand. Wat Phu Tok is a quiet mountain and a place of peace and respect where many climb to the summit to practice meditation. Ajarn Juan was killed in a plane crash on a trip to visit Her Majesty the Queen and his elaborate mausoleum is at this site also.
For those interested in muay Thai boxing lessons on a long-term basis, go to the boxing stadium beside the Grand Hotel and speak to ex-Thai boxing national champion Ajarn Lart, a friendly local who speaks just enough English. This is the real deal, so do not expect an air-conditioned gym with cushy floor mats surrounded by ceiling-high mirrors.
They have a restaurant there also. Fishing competitions held on the first Sunday of each month. All fish have to be returned to the pond after being caught. 20-kg carp have been caught here.
Catch a 50-minute train to Udon Thani at 13:03 for 11 baht. No trains back in afternoon or evening but can return by mini bus from central bus station near Central Plaza. Last bus back 22:00. The large Central Plaza shopping complex is near the Udon Thani train station. Has lots of shops, places to eat and multiplex cinema with English-language movies.
Every year, the Anou Savari Festival occurs 5-15 Mar, spanning just over one week. Unique to Nong Khai, it is the city's biggest street fair and is held in celebration of the defeat of the Hau rebellions between 1884 and 1886. Street music enlivens the festival while games of Ta Kraw are also played.
The Thai New Year takes place on 13 Apr, spilling over to a few days prior and after this date, from 12-15 Apr. Thais celebrate by participating in Songkran, also known as the water festival. Water is splashed on others as symbolism of a blessing, and traditionally it was the day that Buddha images were cleaned. Songkran always turns into a large water fight and is one of the most popular festivals of the year.
The rocket festivals of Nong Khai normally occur in May, the sixth lunar month, in June, and sometimes July (also known as Bun BângFai). Every year at these times, large rockets are fired into the sky and the crowds gather to watch the event as well as enjoy the music, stalls, and vibrant atmosphere of the festival. Visakha Puja day, the day that Buddha was born, the day of his enlightenment, and the day of his death, marks the beginning of one of the biggest rocket festivals and a parade takes place in celebration. The festival is a lot of fun and traditionally it is held to encourage the clouds to part and water the crops, as well as a way to worship Phaya Thaen, the god of rain. Rockets are usually fired about 10 km from Wat Pho Chai, but a temple festival is normally held at Wat Pho Chai itself. The festival goes on for about a week
The annual Candle Festival is a beautiful street parade which takes place on the day before the beginning of Buddhist Lent. Huge candles are built in the grounds of Wat Chayaporn on the days prior to the festival. On the day of the festival they are paraded on floats through the streets, accompanied by dancing girls, boys in their traditional Siamese costumes and middle aged devotees in their white robes.
Rowing festivals take place in Sep-Oct and involve longboats with crews of up to fifty five rowers each. During the first few weeks of Buddhist Lent, Paan Saa, the rowers begin their practice for the race. The race is a spectacular display of athletic talent and the festivities that surround the event are a must-see for any visitor to Nong Khai.
The most important festival in Nong Khai is at the end of Buddhist Lent. This is when the Mekong Fireballs appear. During this period there are dragon boat races, a big festival in Nong Khai, and at Phon Phisai where the Mekong fireballs are visible.
During late-Oct and early-Nov, the people of Nong Khai hold their version of the Chinese Dragon Festival and it lasts for ten days. It's a fantastic event to attend and involves amazing displays of acrobatics, dancing Chinese lions, dancing dragons, parades, firecrackers, and Chinese opera.
The Loi Krathong Festival is known as the second most important festival of the year and occurs between the middle of the 11th lunar moon to the middle of the 12th lunar moon, which is flood season, making the waters high and ideal for this festival. Krathong are small, floating shrines or lanterns normally made out of bamboo leaves and decorated with flowers, incense, and candles. The floating of the Krathong represents the gratitude of the Thais to the gods for the rain, as well as a blessing and good luck for the year. Loi Krathong involves a krathong parade, krathong-design contests, and Noppamas which are beauty pageants.
