Thailand: Complete Travel Guide

Thailand is the most visited country in Southeast Asia, and it earns that reputation. In a single trip you can move from the chaotic energy of Bangkok to the temple-dotted hills of Chiang Mai, then south to some of the most photogenic beaches on the planet — all on a budget that stretches remarkably far. A full meal of world-class street food can cost a couple of euros, and comfortable guesthouses are within almost any budget.

That mix of variety, easy logistics and low daily costs is exactly why Thailand works for such a wide range of travellers, from first-time backpackers to families and honeymooners. The infrastructure is genuinely good: cheap domestic flights, overnight trains, frequent ferries and ride-hailing apps make getting around simple. The main thing to get right is timing, since the country's weather patterns vary by region.

This guide leads with the practical questions — when to go and what it costs — then covers transport, the key regions and the essentials.

Best Time to Visit

Thailand has three broad seasons, and they shift depending on which coast you're on.

• Cool and dry (November to February): The best all-round window for most of the country — Bangkok, Chiang Mai and the Andaman coast (Phuket, Krabi, Phi Phi) all shine. It's peak season, so book ahead.
• Hot season (March to May): Very hot and humid, especially inland; Chiang Mai can also suffer smoky "burning season" haze around March. Beaches stay appealing.
• Rainy season (roughly June to October): Green, cheaper and quieter, with short heavy downpours rather than all-day rain. Note the two coasts differ: the Gulf islands (Koh Samui, Koh Phangan, Koh Tao) are often driest around June to September, when the Andaman side is wettest.

If you only have a fixed window, December to February is the safest bet for combining Bangkok, the north and the Andaman beaches.

What a Trip to Thailand Costs

Thailand is one of the best-value destinations anywhere. Using our verified budget data, a day in Bangkok works out roughly as follows:

• Backpacker: around €27/day (hostel, street food, BTS Skytrain and boats, temple entries)
• Mid-range: around €103/day (a comfortable hotel, restaurant meals, rooftop bars and day trips)
• Comfort/luxury: around €278/day (high-end hotels, fine dining, private tours)

The islands and Chiang Mai can run below Bangkok on a backpacker budget, though beach resorts in high season push the top end higher. Model your own numbers with our trip cost calculator.

Flights. Thailand is a major regional hub, so connections are frequent and reasonable. Based on our verified route data, Bangkok to Hanoi is around €60 one-way, Delhi–Bangkok around €120, Tokyo–Bangkok around €200 and Bangkok–Bali around €100 — handy figures if you're threading Thailand into a wider Asia trip. Domestically, low-cost carriers like AirAsia and Nok Air make internal hops cheap.

Getting Around

• Domestic flights: AirAsia, Nok Air and Thai Lion connect Bangkok with Chiang Mai, Phuket and Krabi cheaply — often faster and barely pricier than the train once you factor in time.
• Overnight trains: The Bangkok–Chiang Mai sleeper is a classic 12-hour journey and an experience in itself.
• Ferries and speedboats: The way between southern islands; schedules thin out in rainy season.
• Grab: Thailand's main ride-hailing app, widely used in Bangkok and larger cities; clearer than negotiating with taxis.
• Tuk-tuks and songthaews: Fun for short hops, but agree the fare before you get in.

Top Destinations

Bangkok

Chaotic, vibrant and hard to leave: the Grand Palace, Wat Arun, floating markets, Khao San Road and rooftop bars with skyline views. Our Bangkok guide breaks down neighbourhoods and costs.

Chiang Mai

The laid-back north — mountain temples, night markets, cooking classes and ethical elephant sanctuaries. A favourite base for slower travel.

The Southern Islands

Koh Tao for diving, Koh Lanta for calm, Koh Phi Phi for its famous scenery, Koh Samui for resorts, and Krabi/Railay for climbing and hidden beaches.

Phuket

The largest island and a major gateway, with beaches, nightlife in Patong and day trips out to the Phi Phi and James Bond islands.

Thai Food

• Pad Thai — stir-fried noodles with shrimp, peanuts and lime
• Som Tam — spicy green papaya salad
• Tom Yum Goong — hot-and-sour shrimp soup
• Massaman Curry — a mild, aromatic curry with Persian roots
• Khao Soi — northern curry noodle soup, a Chiang Mai must
• Mango Sticky Rice — the classic sweet finish

Suggested Itinerary

A well-balanced first trip gives Bangkok two or three days — the Grand Palace, a couple of temples, the markets and one rooftop evening — then flies north to Chiang Mai for two or three nights of temples, cooking classes and an ethical elephant sanctuary. From there, fly south for the beaches: pick one island region rather than trying to see them all, whether that's Krabi and the Andaman coast or the Gulf islands, depending on the season. Ten days to two weeks covers this loop without rushing; the cheap domestic flights mean you lose little time moving between regions.

Practical Essentials

• Visa: Many nationalities can enter for tourism without a visa for short stays, and the visa-exemption period has been extended for several countries in recent years. Rules change, so confirm the current entry requirements for your nationality with an official source before you travel.
• Currency: The Thai baht (THB). Cash is king for street food and markets; cards work in hotels, malls and larger restaurants.
• Water: Don't drink the tap water — bottled water is cheap and everywhere.
• Insurance: Strongly recommended. Healthcare is good and affordable, but a motorbike accident can be costly, and many travellers underestimate the risk of renting scooters.
