Here is the list of Bangkok’s Grand Place and Wat Phra Kaew closing dates for 2015. Please note that the list is subject to change so if you want to be 100% sure there is a contact number at the bottom of the list. Sometimes just parts of the complex are closed to visitors.
Always be careful of those scammers and con artists who hang around outside the Grand Place telling you the Palace is closed. Go check for yourself at the MAIN entrance on the north side of the complex.
The Grand Palace does not admit visitors after 3:30pm and is open from 08:30am until 4:30pm
