Home of Siam’s kings since 1782, the Grand Palace is Bangkok at its most dazzling: gilded spires, mirrored mosaics and the Emerald Buddha, the most revered image in Thailand. It is the one ticket in the city that everyone queues for, and it earns it.
Gates open at 8:30am; be there for opening and do Wat Phra Kaew first, ahead of the tour groups. Anyone outside telling you the palace is closed is running a scam. Walk past.
Take the Chao Phraya river boat to Tha Chang pier and walk five minutes. Cover knees and shoulders, or rent a wrap at the gate. Wat Pho and its Reclining Buddha are ten minutes south on foot.
