Bangkok Travel Tips: What to Know Before You Go

Before you go to Bangkok

Bangkok rewards travelers who understand three things before arriving: the heat dictates the shape of your day, the river and rail lines dictate where you can realistically go, and cash still matters in the places worth eating at. Everything below is specific to how the city actually works rather than generic advice.

Plan your day around the heat, not the map

Bangkok sits a shade above 30°C for most of the year with humidity that rarely drops below uncomfortable, and the hot season from March to May regularly pushes past 35°C. The practical consequence is that outdoor sightseeing — the Grand Palace, Wat Pho, Chatuchak, the canal neighbourhoods of Thonburi — belongs to the window between roughly 07:30 and 11:00. Temples open early and are quietest then, and you will cover twice the ground you would at 14:00.

From midday to about 16:00, plan indoor or water-based activity: an air-conditioned mall such as ICONSIAM or Siam Paragon, a long lunch, a massage, the Jim Thompson House, or a Chao Phraya boat where the breeze does the work. Evenings from 17:00 belong to markets, rooftop bars and street food, when the temperature drops enough to walk comfortably again. From roughly June to October a heavy late-afternoon downpour is common; it usually clears within an hour, so it is worth timing an indoor block around it rather than abandoning the day.

Money: cards, cash and where each one works

Malls, hotels, chain restaurants and Grab all take cards without issue, but the food that makes Bangkok worth visiting — street stalls, Chinatown vendors, market kitchens, small shophouse restaurants — is overwhelmingly cash or Thai QR payment. Carry 500–1,000 baht in small notes and coins per person per day; vendors frequently cannot break a 1,000 baht note early in the day.

• Thai ATMs charge a fixed foreign-card fee of around 220 baht per withdrawal regardless of amount, so withdraw larger sums less often rather than topping up daily.

• Always decline the ATM's offer to convert to your home currency — choosing to be charged in baht avoids a poor built-in exchange rate.

• Airport currency counters inside the terminal give noticeably worse rates than city exchange booths such as those in Silom or Pratunam; change a small amount on arrival and the rest in town.

• Tipping is not expected at street level. Rounding up a taxi fare or leaving 20–50 baht after a sit-down meal is generous, and upmarket restaurants often add a 10 percent service charge already.

Getting around without losing the day to traffic

Bangkok's traffic is genuinely severe between roughly 07:00–09:30 and 16:30–20:00, and a 6 km taxi trip that takes 15 minutes at 11:00 can take 50 at 18:00. Treat the BTS Skytrain, MRT metro and the Chao Phraya express boats as the default for any journey they cover, and save taxis and Grab for late nights, luggage and places the rail lines miss such as the older Rattanakosin temple district.

• Insist on the meter in a street taxi, or simply use Grab or Bolt where the fare is agreed upfront — a driver quoting a flat price for a city trip is always more expensive.

• Tuk-tuks are a short-hop novelty, not transport: they are usually pricier than a metered taxi and negotiating is expected before you get in.

• The orange-flag Chao Phraya express boat is the cheapest way to move along the river; the blue-flag tourist boat costs several times more for the same route.

• Rush-hour BTS platforms at Siam and Asok fill quickly — buy a stored-value Rabbit card or use contactless to skip the ticket-machine queue.

Etiquette that actually matters locally

• The monarchy is protected by strict lèse-majesté laws; criticism, jokes or defacing images of the royal family, including on banknotes, are treated as serious criminal offences.

• Remove shoes before entering temple buildings, homes and many small shops and guesthouses — slip-on footwear makes the day easier.

• Never touch anyone's head or point the soles of your feet at a person or a Buddha image; both read as insulting.

• Women should avoid handing objects directly to or brushing against a monk; place items down or pass them via a man.

• Public displays of anger cause loss of face on both sides. Complaints delivered calmly and with a smile are resolved far faster than raised voices.

Health, water and staying comfortable

Tap water is not for drinking; bottled water is inexpensive everywhere and ice in restaurants and reputable street stalls is made from purified water, so it is generally safe. Street food itself is not a health risk when the stall is busy and cooking to order in front of you — high turnover means fresh ingredients, and the busiest stall on a street is usually the safest choice.

Bangkok's private hospitals — Bumrungrad and Samitivej among them — are internationally accredited, English-speaking and used routinely by visitors, but they bill upfront, so travel insurance that covers medical treatment is worth having. Pharmacies are widespread and can dispense a lot without a prescription. Mosquitoes are most active at dawn and dusk during the rainy season; repellent matters more in the leafier riverside and park areas than in the built-up commercial districts.

Practical tips for Bangkok

• Buy a Rabbit card at any BTS station — S$50 works pay-as-you-go for BTS + Skywalk connections.

• Wear long trousers and cover shoulders at all temples — sarong rentals available for 20 THB.

• Ignore anyone at the Grand Palace saying it's 'closed today' — that's the gem-shop scam.

Staying safe and comfortable

Local emergency number: 191.

• Watch for gem-shop and tailor-shop touts near the Grand Palace and Khao San Road.

• Only use metered taxis or Grab — refuse flat-rate offers from airport touts.

• Emergency 191 (police), 1155 (tourist police with English speakers).

Visas and entry

Entry policy: mixed, typically up to 60 days. Most Western, GCC, ASEAN, Japanese, Korean and Chinese passports enter visa-free 30–60 days (extended to 60 for many nationalities since mid-2024). Longer stays use eVisa; passport must be valid 6+ months.

Budgeting your trip

Accommodation is the largest controllable cost in Bangkok. Compare live rates for your dates and neighbourhood shortlist before locking in flights — the difference between areas is often larger than the difference between travel weeks.
