Every Sunday and on Buddhist holidays, chartered buses depart from Sanam Luang (near the main gate of Thammasat University), from Jatujak Park (opposite the Northern Bus Terminal) and from the Victory Monument (in front of the TV 5 Building). Look for passengers dressed in white.
Buses leave for the temple from 07.00-08.00 H. traveling direct. Buses return to Bangkok from the temple’s bus park between 18.30 H.
