Bangkok, more than a transit night
The gateway to mainland Southeast Asia and the city almost everyone passes through. Two or three nights, the river as the way to see it, and the arrival formality that catches people out.
What Bangkok actually is
A city of eleven million with no single centre, built on a river and a filled-in canal network, and it is the transport hub of mainland Southeast Asia. Almost every trip in this region touches it. That is why it is on this list, and it is also why so many people give it a single transit night and dismiss it.
The old city on the river — Rattanakosin — is a walkable district containing the Grand Palace, Wat Pho and a working temple quarter, and it feels nothing like the Sukhumvit high-rise Bangkok that most first-time visitors sleep in. Choosing the riverside over Sukhumvit changes what the city is by about half.
The heat and the traffic are real. Bangkok is genuinely hot from March to May, and road journeys of five kilometres can take an hour. The answer is the river and the two rail systems: the Chao Phraya express boat, the BTS Skytrain and the MRT together cover most of what a visitor needs, and none of them sits in traffic.
How many nights
Two, minimum, and three if this is your first time in Asia. Two nights gives one full day: the Grand Palace and Wat Pho early, Wat Arun across the water, and an afternoon on the express boat. Three adds Jim Thompson House, a market morning, and time to eat properly, which in this city is a legitimate use of a day.
One transit night is what most people do and it is a waste of a good city. If your itinerary passes through twice — in at the start, out at the end — split it: one night on the way in while you are jet-lagged, two on the way out when you are not.
Bangkok is also where the overnight train to Vientiane leaves from, and where the flight to Siem Reap goes, so the routing usually decides for you.
The arrival card everyone forgets
Every foreign national must file the TDAC at tdac.immigration.go.th for every entry, including entries overland from Laos and re-entries after a border run. The submission window opens exactly 72 hours before arrival and it costs nothing. Sites charging a fee for it are not the government.
On the visa itself: 93 nationalities enter visa-free for 60 days, extendable once for 30 more at any immigration office for 1,900 baht. Thailand's cabinet approved reducing the exemption to 30 days in May 2026, but as of late August 2026 the change had not been published and 60 days was still being stamped. We confirm the position applying to your dates before you travel.
When to go
| Months | What it is like |
|---|---|
| November to February | The best window. Dry, 24 to 32 degrees, and genuinely comfortable in the evening. |
| March to May | The hot season. 35 to 40 degrees with high humidity, and April is the worst of it. |
| June to October | Wet season. Sharp afternoon downpours rather than all-day rain, and some street flooding. |
| Mid-April | Songkran. Three days of water fights and a city that half empties. Enjoyable if you expect it and miserable if you do not. |
How to get there and around
Suvarnabhumi (BKK) is 30 kilometres east; Don Mueang (DMK) is 25 kilometres north and handles most low-cost carriers. Transfers run 45 to 90 minutes depending on the hour. The Airport Rail Link from Suvarnabhumi is fast and useful if your hotel is near a BTS interchange.
Krung Thep Aphiwat is the main railway station and it is where the overnight train to Vientiane leaves, at 20:25, arriving at Khamsavath at 09:05. A second-class air-conditioned lower berth is about 874 baht. Trains also run north to Chiang Mai overnight.
Flights to Siem Reap take about an hour and to Phnom Penh about seventy-five minutes. Both are, in 2026, the only way to reach Cambodia from Thailand: every land border has been closed since late June 2025.
In the city, use the express boat, the BTS and the MRT. A taxi in the afternoon peak is a way of watching the city rather than crossing it.

When to skip Bangkok
- If you have already spent time here and the trip is short. It is easy to route around with a same-day connection.
- April, if heat is a problem. Bangkok in April is 40 degrees and humid.
- If you were planning to continue to Cambodia by road. You cannot, and the itinerary has to be rebuilt around a flight.
- If crowds at Songkran are not your idea of a holiday. Mid-April is a specific commitment.
- If you booked a hotel on Sukhumvit because it was cheap and then wonder why the city feels like an airport concourse. Stay on the river.

Questions travellers ask most
Is the Grand Palace worth the queue?
Once, and early. It opens at 08:30 and by 10:00 it is very busy. Wat Pho next door is calmer, cheaper and, for many people, better.
Dress code is enforced: shoulders and knees covered, no see-through fabric. They will sell you a wrap at the gate if you get it wrong.
Riverside or Sukhumvit?
Riverside, if the city is the point. You get the express boat at the door, the old town within walking distance, and a completely different set of streets.
Sukhumvit is better connected to the airport rail and has more international restaurants. It is also anywhere.
Do I really need to file the arrival card?
Yes, every foreign national, every entry, including overland from Laos. It is free, it takes five minutes, and the window opens 72 hours before arrival.
Do it at tdac.immigration.go.th and nowhere else.
Can I reach Cambodia overland from Bangkok?
Not in 2026. Every Thailand–Cambodia land crossing, including Poipet–Aranyaprathet, has been closed since late June 2025 and no reopening date has been announced.
Flights operate normally. See crossing borders.
