The Ubon Ratchathani Candle Festival is one of Thailand’s most spectacular and meaningful celebrations. The event is a blend of Buddhist devotion, local artistry and big-scale parades that light up this northeast Thai city every July.
History and background
The festival is closely tied to two important Buddhist holy days: Asanha Bucha and Khao Phansa. Asahna Bucha Day commemorates the Buddha’s first sermon, while the day after is Khao Phansa Day. This marks the start of the Phansa period (sometimes referred to as Buddhist Lent), a three-month rainy-season retreat when monks traditionally stay in their monasteries to study and meditate.
Before electricity, villagers donated large candles at Phansa to their local temples so monks could read scriptures and move safely around the monastery at night. Over time, this simple act of merit evolved into a creative competition as communities tried to outdo each other with bigger and more beautifully decorated candles.

In Ubon Ratchathani, this tradition has grown into the country’s most elaborate candle procession. Giant beeswax candles and ornate wax sculptures depicting scenes from Buddhist and Hindu mythology are placed on floats. The floats represent temples, schools and government offices in Ubon. The floats and wax carvings are then paraded through the city on Khao Phansa morning, accompanied by musicians and dancers in traditional Isaan costume. 
The festival stretches over several days, with candles paraded from local temples to Thung Si Mueang Park in the city centre on Asahna Bucha Day. They remain there overnight with the park transformed into a festival zone with music and food. The main parade takes place the following day on Khao Phansa Day.

Celebrating local culture
For Ubon residents, the Candle Festival is far more than a photogenic parade. This age-old radiation is filled with spiritual significance, with the offering of candles symbolising bringing light and wisdom into life. The festival marks the start of a more reflective season, when many Thais try to give up bad habits, and young men may ordain as monks for the Phansa period.

There is much community pride on show, and winning the candle contest is a major honour for a temple or community. Neighbourhoods spend weeks or months preparing their floats. Artisans, monks, students and volunteers all pitch in as wax is melted, frames are built, and fine details are carved.
The designs often show stories from Buddhist scriptures or the Ramayana, alongside naga serpents, garudas and other mythological figures, helping to keep Isaan and wider Thai cultural traditions alive.

The festival plays an important role in the local economy because it attracts visitors from across Thailand and abroad, filling hotels and restaurants and supporting local craftspeople who sell textiles, snacks and souvenirs. 
There’s also a philosophical side; after the festival, the wax sculptures are eventually melted down and reused, echoing the Buddhist teaching that nothing in life is permanent. 
Practical advice for travellers
The festival takes place around Asanha Bucha and Khao Phansa, usually in July, but exact dates change each year with the lunar calendar. Check the current year’s schedule from official tourism sources before you book, and aim to be in Ubon for at least three or four days to see both the candle displays and the main parade.
Most events are focused around Thung Si Mueang Park in central Ubon Ratchathani, where floats are parked and illuminated at night. The big daytime processions usually run along major roads (including Upparat Road) near the park.
Ubon Ratchathani is about 600 km northeast of Bangkok and is served by daily flights, overnight trains and long-distance buses. If you want to attend the festival, you will need to book transport and accommodation well in advance.
Visit local temples in the days leading up to Asahna Bucha to watch artisans putting the finishing touches to the candles up close.
For the main parade on Khao Phansa morning, aim to arrive early (before 8 am) if you want a good viewing spot in the shade. The parade lasts for several hours with floats, marching bands and dance troupes.
As with any festival in Thailand, there is an abundance of street food stalls to feed the crowds, and this is a great chance to try Isaan favourites like gai yang (grilled chicken), khao niao (sticky rice), som tam (papaya salad) and local desserts.
The Candle Festival has deep religious roots, and a bit of cultural sensitivity goes a long way. Dress modestly and cover your shoulders and knees, especially if you visit temples or join processions.
Avoid climbing on floats or touching the wax carvings; they’re sacred offerings and very fragile. Always ask before photographing monks or close-ups of local people, especially during prayer or merit-making.
As alcohol sales are typically banned on Asanha Bucha and Khao Phansa, plan your evenings around food and performances rather than nightlife.
