On a sunny Sunday in May, Boun Bang Fai or Rocket festival has been held at Na Son village, about 50km away from Vientiane Capital.
The festival is a ritual for rain, which is necessary to plant rice.
Rocket festivals can be seen anywhere else all over Laos even in small villages, but you need to contact a travel agency or local people if you want to join the festival since the schedule is usually uncertain until just before.
