Why Bangkok is worth visiting
Bangkok grew from a river-trading village into Siam's capital in 1782, when King Rama I built the Grand Palace on the eastern bank of the Chao Phraya and raised Wat Phra Kaew inside its walls to house the Emerald Buddha. That founding core, Rattanakosin, still holds the temples and palaces that give the city its skyline of gilded spires, now surrounded by a modern metropolis of malls, skytrains and street food that never quite goes quiet.
Neighbourhoods to know
Rattanakosin keeps the Grand Palace, Wat Pho and the National Museum inside its old city walls. Yaowarat and Phahurat form Chinatown, a dense grid of gold shops, Chinese temples and food stalls. Silom and the riverside mix office towers with night markets, while Sukhumvit runs the length of the BTS Sukhumvit line through shopping malls, restaurants and nightlife.
When to go and for how long
The cool season from November to February is driest and most comfortable for temple hopping. The hot season builds through March and peaks in April, and the rainy season runs from mid-May to October, with September usually the wettest month and short afternoon downpours rather than all-day rain. Three to four full days cover the main sights at an easy pace.
Getting around
The BTS Skytrain and MRT subway cover the newer districts quickly and cheaply, while the Chao Phraya Express Boat threads the river past Rattanakosin and Chinatown, avoiding the road traffic Bangkok is known for. Tuk-tuks and metered taxis fill the gaps, though a taxi in gridlock can take far longer than the same trip by rail or river.
