Practical info
Know before you book
The things that change a decision — not a retelling of the guidebook.
The word “sanctuary” is not regulated
Anyone can use it. The practical test is the itinerary: genuine sanctuaries do not offer riding, bathing on demand or performances, and they say so plainly. If riding appears anywhere on the page, it is a camp, whatever it calls itself.
The two coasts have opposite monsoons
The Andaman side — Phuket, Krabi, Khao Lak — is wettest from May to October. The Gulf side — Koh Samui and its neighbours — gets its heaviest rain from October to December. In almost any month one coast is in good shape, which is worth knowing before you fix a destination.
The north has a burning season
From roughly February to April, agricultural burning gives Chiang Mai some of the worst air quality readings in the world for weeks at a time. It is the single biggest reason to move a northern Thailand trip to another month.
The Grand Palace enforces its dress code
Shoulders and knees covered, no sheer fabric, no sandals in some areas. Sarongs are rented at the gate and the queue for them is long. Related: anyone who approaches you outside to say the palace is closed today is running a scam — it is not.
In Bangkok the boat beats the taxi
The river express and the Skytrain move at a fixed speed while the roads do not. At rush hour a three-kilometre taxi ride can take forty minutes. Plan the day around the BTS lines and the Chao Phraya rather than around the map.
Songkran is a nationwide water fight
The Thai new year, 13 to 15 April, and the whole country throws water in the street for three days. It is joyful and completely unavoidable — nothing is dry and nothing runs normally. Loy Krathong in November is the quieter, prettier festival.

Frequently asked
Thailand: common questions
How many days do you need in Thailand?
Ten days is the usual shape: three in Bangkok, three in the north around Chiang Mai, and four on an island. Two weeks lets you slow down rather than adding places — the internal flights are cheap but they cost half a day each.
What does a tour in Thailand cost?
Bangkok sits at a median of €64 in our index of 50 cities and Chiang Mai at €42, against a global median of €60. The gap is the point: the north is markedly cheaper, and Bangkok’s figure is lifted by full-day trips to Ayutthaya and the floating markets.
When is the best time to visit?
November to February for the country as a whole — dry, cooler and busy. If you are only going to the islands, pick the coast by month instead: the Gulf is the dry one in June to September, the Andaman in December to March.
How do I choose an ethical elephant experience?
Read the itinerary rather than the name. No riding, no shows, no chains, and no forced bathing sessions where dozens of visitors scrub the same animal. Reputable places limit group sizes and keep you at a distance for part of the visit.
Are tours run in English?
Everywhere in the destinations on this page. Thailand has one of the largest and most competitive English-language tour markets in Asia, which is also why the prices are what they are.
