The Grand Palace in Bangkok, Thailand, is like a royal wonderland that has been the official residence of the Kings of Siam since 1782. It's a massive complex with beautiful buildings, halls, and gardens. The palace has rich history and stunning architecture and it's a great addition to any Bangkok tour.
The opening hours are from 8:30am-3:30pm and the last admission is at 3:00pm. It can also get extremely busy here with long lines so I recommend going as early as possible.
You will need to dress modestly to enter so that means women covering shoulders and knees and men covering shoulders. If you don't have anything appropriate to wear, you can rent clothing at the entrance.
