Thailand Travel Guide: Essentials, Local Tips & Mobile Data

Bangkok, islands and the north: money, transport, etiquette, when to go, curated traveler tips, and the easiest way to get mobile data.

Thailand

Thailand remains Southeast Asia's great all-rounder: Bangkok's street food and temples, the jungles and hill towns of the north around Chiang Mai, and an island for every taste, from party-hard Phangan to sleepy Ko Lanta.

It is easy, affordable and welcoming, but rewards travelers who dodge the tourist-trap circuit: eat at busy street stalls, learn a polite wai and a few Thai phrases, and treat temples with covered-shoulders respect.

The heat is part of the deal, and so is the sweetness of the welcome. A wai, a smile, and not raising your voice will carry you further than any guidebook phrase. Temples are active religious sites, not backdrops — cover up, take the shoes off, and do not climb the ruins for a better angle.

Bangkok plus the north, or Bangkok plus one island group, is enough. Trying to 'do' the whole country in two weeks is how you spend your holiday in airports and minivans. Stay longer in fewer places. Thailand rewards the second week in a town you almost skipped.

Traveler tips

Tips from fellow travelers

Real advice from people who have been to Thailand, curated by our team with links to the original sources.

Insist on the meter or use Grab

Bangkok taxis that refuse the meter and tuk-tuks quoting flat fares are charging several times the real price. Grab removes the negotiation entirely and shows the fare up front.

Skip the gem shops and suit deals

Anyone telling you a temple is closed and offering an alternative tour is running the country's oldest scam, usually ending at a gem or tailor shop. Temples rarely close; walk to the entrance and check yourself.

Eat where the plastic stools are full

The best food is at street stalls and shophouses packed with locals at plastic tables. High turnover means fresh ingredients - a busy som tam stall beats an empty air-conditioned restaurant.

The king and the monarchy are not a joke

Lèse-majesté laws are real. Do not make jokes about the royal family, stand still for the anthem in cinemas and on the BTS, and treat portraits with the same respect locals do. It is the one topic that is never casual.

Songthaews and boats beat another taxi argument

Shared red trucks in the north and longtail boats in the south are how a lot of Thailand actually moves. Agree the price before you sit down, or use Grab in the cities and stop negotiating altogether.

eSIM plans

Stay connected in Thailand

Grab rides, island ferry bookings and translation apps make data essential in Thailand from hour one. A Thailand eSIM costs pocket change, activates before you land in Bangkok, and saves the arrivals-hall SIM queue after a long flight.

Island ferries change, Grab drivers need a pin, and the best stall is always three alleys over. An eSIM is the cheapest insurance in Thailand — and it means you never have to find a phone shop on an island when the plan goes sideways.
