What Is Boun Bang Fai (Rocket Festival)?

Boun Bang Fai (also Bun Bang Fai) is a Theravada Buddhist festival celebrated across Laos and northeastern Thailand. In Vientiane the event is centred around That Luang, the golden stupa at the heart of the city, and the village temple grounds across the Vientiane plain. Teams build rockets from bamboo and PVC pipe, stuffing them with a black powder propellant mix. The rockets are fired vertically from wooden launch frames in competitive heats: the winner is the rocket that travels highest before descending. Rockets that fail to fire are traditionally punished with the builder being thrown into the mud of the adjacent paddy field, which is considered both a fine and a fertility blessing.

For travellers, the festival divides into the urban Vientiane programme around That Luang and the village festivals occurring simultaneously in the surrounding districts. The That Luang complex (That Luang Neua district, 4 kilometres northeast of the city centre) is the most accessible location, with a procession, market, and performances. The village festivals are more spontaneous and raw: tuk-tuk drivers around the Morning Market (Talat Sao) know the day's local venues and will negotiate a half-day transport fee. Vientiane's hostel district along Setthathirat Road is 20 minutes by tuk-tuk from That Luang.

What to Expect

Day-by-day breakdown

Day 1

Procession day and That Luang market

The opening procession moves through the city towards That Luang from late morning. Participants carry offerings to the stupa; the procession includes music, traditional dance, and elaborately decorated floats carrying the rockets before competition. The market around That Luang opens from dawn, selling Lao street food (khao niew, larb, tam mak hoong), religious items, and festival goods. The atmosphere is participatory: travellers who dress modestly (covered shoulders and knees near the stupa) are welcomed without issue.

Day 2

Rocket competitions and village festivals

Competition day runs from early morning at the designated launch sites outside the city, typically in open fields off Route 13 north of Vientiane. Tuk-tuks and songthaew trucks run informal services from Talat Sao bus station to the launch areas from 7am. The launches are rapid and intermittent throughout the day: watching 20–30 rockets fired over three hours is typical. The mud-dunking of unsuccessful builders follows each failed launch. Village festivals in the surrounding districts run concurrently, with rice wine (lao-lao) flowing freely.

Practical Tips

Ask your hostel which village festival to attend

The village Boun Bang Fai events outside Vientiane are more authentic than the city-centre programme but require local knowledge to find. Hostels and guesthouses on Setthathirat Road and the Mekong riverfront typically arrange group tuk-tuk transport on competition day for USD 5–8 per person return. Book the evening before.

Dress modestly near temples and during processions

Boun Bang Fai has a Buddhist ceremonial component centred on That Luang and the temple grounds. Covered shoulders and knees are required inside temple grounds. On the streets and at the launch sites, standard travel clothing is fine. The mud-dunking areas near the launch frames get genuinely wet and muddy: wear clothes you can wash.

Lao kip: change money at commercial banks, not hotels

The Lao kip (LAK) is not internationally traded. Change USD, EUR, or Thai baht at BCEL Bank or Lao Development Bank on Lane Xang Avenue, which give the best rates. Hotels and exchange booths near Talat Sao give 8–15% less. ATMs in Vientiane dispense kip and baht; foreign transaction fees average LAK 10,000 (40p) per withdrawal.

Vientiane in May is hot and building to wet season

May in Vientiane averages 33–36°C with high humidity and increasing afternoon rainfall as the wet season approaches. Festival activities run in the morning and early afternoon specifically to avoid the midday and afternoon heat. Bring sun protection and at least 2 litres of water for outdoor events. Afternoon thunderstorms are possible from 2pm onwards.

The Mekong riverfront is the evening gathering point

Vientiane's Mekong riverfront promenade (Fa Ngum Road) is the social centre during the festival period. The night market along the riverside between Khouvieng and Fa Ngum runs from 5pm with food stalls, Beerlao stands, and informal music. The stretch between the Nam Phu fountain and the COPE Visitor Centre is most active. Beerlao large bottles (630ml) cost LAK 15,000–20,000 (60–80p) at riverfront stalls.

Combine with a Mekong crossing to Nong Khai, Thailand

The Friendship Bridge crossing between Vientiane and Nong Khai, Thailand is 22 kilometres from the city centre. Songthaew trucks to the bridge depart from the central bus station. A Thai visa-on-arrival (THB 2,000, approximately £45) is available at the border for most nationalities. Nong Khai has direct overnight trains to Bangkok (10 hours) if you are continuing south.
