The Royal Cremation is set for 26 October 2017
The cremation will take place at the royal cremation at Sanam Luang (in front of the Grand Palace).
It will be an grand happening and a milestone in the history of Thailand. And it might be a great experience to be in Thailand that week. But it might also change your holiday planning a bit. So if you are planning to travel in Bangkok or Thailand then it might be a good idea to take this into account and inform yourself about what is happening and what might be closed. I assume that the Grand Palace will be closed in that week.
