First Time in Thailand? Everything You Need to Know (2026)

Thailand is one of those places that’s genuinely easy to travel in — once you know the unwritten rules. The problem is that nobody writes them down until you’ve already overpaid for a tuk-tuk ride and accidentally offended someone at a temple. So here they are.

Getting from BKK to the city

Suvarnabhumi Airport (BKK) is about 30km east of central Bangkok. You have four realistic options:

• Airport Rail Link (ARL): 45 baht, 30 minutes to Phaya Thai station. Cheap, fast, air-conditioned. Runs from 5:30am to midnight. This is what you should take unless you have a specific reason not to.
• Grab (ride-hailing): 250-400 baht depending on time, 30-90 minutes depending on traffic. Book from the app, meet at level 1 pickup zone. More expensive but door-to-door.
• Metered taxi: Join the official taxi queue on level 1. Insist on the meter — say “meter, krap/ka” before getting in. Expect 250-350 baht plus tolls (around 75 baht on the expressway). If the driver refuses the meter, get out and take the next one.
• Tuk-tuk: Not from the airport. Just don’t. They don’t operate at BKK, and anyone who approaches you offering a “tuk-tuk taxi” is freelancing.

If you’re landing at Don Mueang (DMK, the budget airline airport), the situation is similar but without the rail link. Grab or metered taxi are your best options.

Daily transport: BTS, MRT, boats, and Grab

Bangkok’s BTS Skytrain and MRT subway cover a surprisingly large part of the city. Buy a Rabbit card for the BTS (200 baht deposit + whatever you load) or just use single-ride tokens. The MRT takes its own stored-value card or tokens. Yes, it’s annoying that they’re not interchangeable. Welcome to Bangkok.

Grab is your best friend for everything the trains don’t reach. It works exactly like Uber — set your pickup and destination, confirm the price, pay in cash or card. Grab bikes (motorcycle taxis through the app) are faster in traffic and cost about half. They’re also terrifying the first time, according to virtually every traveler who tries them. You get used to it.

The Chao Phraya river boats are useful for reaching riverside temples and Khao San Road area. The orange-flag express boats cost 15 baht per ride and stop at every major pier. Learn the pier numbers for the spots you want to visit.

Street food — yes, eat it

The number one question first-timers ask is whether street food is safe. Yes. With one rule: eat where locals eat. A stall with a line of Thai people at lunchtime is safe. A stall that caters exclusively to tourists on Khao San Road is a roll of the dice.

Other practical tips: watch for high turnover (food that sits around gets risky), make sure meat is cooked fresh (not pre-cooked and sitting under a heat lamp), and ease into the spice levels. When they ask how spicy, “nit noi” (a little) is your friend for the first few days.

The ice is fine. This comes up constantly. The ice in drinks at restaurants and street stalls is factory-made and purified. It’s the tap water you don’t drink, not the ice.

Temple etiquette

Thailand is a Buddhist country and temples are not tourist attractions — they’re active places of worship. The basics:

• Cover your shoulders and knees. Bring a scarf or sarong. Some temples lend them but don’t count on it.
• Remove your shoes before entering any building.
• Never point your feet at a Buddha image. Sit cross-legged or tuck your feet behind you.
• Women cannot touch or hand things directly to monks. If you need to give something, place it down for them to pick up.
• Don’t climb on Buddha statues for photos. This should be obvious but it happens enough that signs exist.

Scams to know about

Thailand is safe but scams are part of the ecosystem. Know these and you’ll avoid 90% of them:

• The gem store: A friendly local tells you there’s a special government gem sale, one day only, amazing prices. There is no government gem sale. The gems are worthless. This scam has been running for decades and still works on first-timers.
• Tuk-tuk “tours”: A driver offers to take you to five temples for 20 baht. The catch: the route includes “quick stops” at a tailor shop and gem store where the driver earns a commission from your purchases. If the price sounds too good, it is.
• “Temple is closed”: Someone near a popular temple tells you it’s closed for a holiday or ceremony and helpfully redirects you to another location (usually a shop or overpriced tour). Check the temple yourself. It’s almost never actually closed.
• Jet ski damage claims: In island destinations, some jet ski operators claim you damaged the vehicle and demand thousands of baht. Photograph the jet ski before you ride it. Better yet, skip jet skis entirely.

Monsoon seasons and when to go

Thailand has three seasons: hot (March-May), wet (June-October), and cool (November-February). The cool season is the most popular for tourists and the most comfortable. But the wet season isn’t the nightmare people imagine. It usually rains hard for an hour in the afternoon and then stops. Prices are lower, crowds are thinner, and the landscape is green instead of brown.

The exception: islands on the Andaman side (Phuket, Krabi, Phi Phi) get genuinely rough weather June through September. Ferries cancel, beaches are dangerous, and some smaller operations shut down. The Gulf side (Koh Samui, Koh Phangan, Koh Tao) has different weather patterns and peaks later, around October-November.

SIM cards and connectivity

Buy a tourist SIM at the airport. AIS, DTAC, and TrueMove all have counters past immigration. A 7-day unlimited data SIM costs about 300 baht. A 15-day one is around 500. They’ll set it up for you — just hand over your passport and phone.

This is one of those things where spending 15 minutes at the airport saves you hours of frustration later. Having data means Grab works, Google Maps works, and you can look up “is this temple actually closed today” before believing the guy on the street.

The thing nobody tells first-timers

Slow down. Bangkok alone could fill a week, but most people try to cram Bangkok, Chiang Mai, and three islands into ten days. You’ll spend more time at bus stations and airports than actually experiencing anything. Pick two or three places and actually be there. Thailand rewards lingering.
