Welcome

Planning a trip to Thailand

Thailand's enduring dominance of the Southeast Asia travel market isn't accidental - it is one of the most functionally excellent travel destinations in the world. The combination of excellent infrastructure, world-class food available at every price point, genuinely spectacular natural scenery (mountains in the north, thousands of kilometres of coast in the south), a temple culture of extraordinary beauty and depth, and a hospitality tradition that consistently ranks among the finest in Asia makes Thailand difficult to beat on almost any metric. More than 35 million visitors arrive each year, and the majority leave planning their return before the flight home lands.

What takes more time to understand is the country's internal diversity. The Thailand of Bangkok - a massive, chaotic, cosmopolitan city of 10 million people with world-class restaurants and some of Asia's best nightlife - is nothing like the Thailand of Chiang Mai, a slower, more Lanna-inflected culture in the cool northern mountains. The Andaman coast (Phuket, Krabi, Koh Lanta) is lush, warm, and rain-dependent; the Gulf coast (Koh Samui, Koh Phangan, Koh Tao) has different weather patterns and a different character. The northeast (Isaan) and deep south have languages, cuisines, and cultural traditions that feel completely distinct from the tourist trail. Understanding which Thailand you want shapes where you go and when.

This guide brings it all together. We have city guides for Bangkok, Chiang Mai, and every major destination, regional overviews for both coasts and the interior, island guides for the Gulf and Andaman archipelagos, practical itineraries for one to three weeks, food guides that go well beyond pad thai, accommodation from beach bungalows to Aman resorts, and the practical information needed to navigate visa changes, monsoon timing, and island transport. Start with the itineraries section if you're planning your first trip.

Where to go

Top Cities in Thailand

Bangkok divides opinion among travellers and rewards those who give it time. The city's scale is overwhelming at first - greater Bangkok has 10–15 million people depending on how you count, sprawls over 1,500 square kilometres, and has traffic that makes it one of the world's most congested cities. The BTS Skytrain and MRT metro make navigating the tourist corridors between Sukhumvit, Silom, and the Old City practical and cheap, but the city's best experiences are in its street-level density: the Grand Palace and Wat Phra Kaew complex (arrive at 8am when it opens), the khlong (canal) network around Thonburi (explored by longtail boat), Chinatown's Yaowarat Road at night, and the neighbourhood of Ari for the Bangkok that Bangkokians actually inhabit. Budget 3–4 nights minimum; most first-timers wish they'd stayed longer.

Chiang Mai, 700 km north of Bangkok, is the country's second city in cultural terms if not in population. The old city moat district contains over 300 temples, including Wat Chedi Luang, Wat Phra Singh, and the silver-smithing temple Wat Srisuphan; the Sunday Walking Street on Wualai Road is the best market in the country. Beyond the temples, Chiang Mai is the gateway to northern Thailand: hill tribe villages, elephant sanctuaries (choose ethical operators carefully), night bazaars, trekking into the Doi Inthanon mountains, and the finest khao soi in the world. Ayutthaya - the former capital of the Thai kingdom, now a UNESCO World Heritage Site of atmospheric ruins - is best as a day trip from Bangkok (90 minutes by train) but rewards an overnight stay to see the ruins in the early morning light.

Big picture

Thailand's Regions

Thailand's six regions each have a distinct character that goes well beyond climate. Central Thailand contains Bangkok and the Central Plains - the heartland of the Thai kingdom, with Ayutthaya and Sukhothai's historical parks, the River Kwai bridge at Kanchanaburi, and the beach resorts of Hua Hin. Northern Thailand (Chiang Mai, Chiang Rai, Pai, Mae Hong Son) is mountainous, cooler, and culturally Lanna rather than Central Thai - the cuisine, architecture, and festivals differ significantly. The northeast (Isaan) is the country's poorest and most authentic region: shared border with Laos and Cambodia, a Khmer-influenced culture, the finest sticky rice and grilled meats in the country, and the extraordinary Mekong river towns of Nong Khai and That Phanom.

The two southern peninsular regions have the beaches and islands that most international visitors come for. The Gulf Coast (Surat Thani, Koh Samui, Koh Phangan, Koh Tao) faces east into the Gulf of Thailand; the Andaman Coast (Phuket, Krabi, Koh Lanta, Koh Phi Phi) faces west into the Indian Ocean. These two coasts have opposite monsoon patterns - when the Andaman gets its heavy June–October rains, the Gulf Coast is dry, and vice versa. Understanding this is the single most important piece of planning knowledge for anyone building a Thailand itinerary. Each regional guide covers climate, transport, the essential towns and landscapes, and the food traditions specific to that part of the country.

Offshore

Thailand's Islands

Thailand has more than 1,400 islands; around 30 are regularly visited by tourists. Choosing correctly depends almost entirely on the time of year, the atmosphere you want, and how much travel time you're willing to spend getting there. The Gulf Islands - Koh Samui, Koh Phangan, and Koh Tao - are accessible by overnight train plus ferry from Bangkok (9–10 hours total) or by short flight from Bangkok Suvarnabhumi. Koh Samui is the most developed, with all-inclusive resorts, an international airport, and a tourist infrastructure comparable to Bali or Phuket. Koh Phangan is known for Full Moon Party (each month at full moon, 30,000 people on the beach) but the northern beaches - Haad Yao, Haad Salad - are peaceful and beautiful outside the party weeks. Koh Tao is the best place in Thailand to learn scuba diving, with clear shallow water, abundant reef fish, and multiple PADI centres.

The Andaman islands are more spectacular visually but require planning around the wet season (May–October). Koh Lanta (open November–April) is the most balanced choice: beautiful beaches, no rowdy party scene, excellent food, family-friendly. Koh Phi Phi is famous and crowded but Maya Bay (the beach from the film "The Beach") remains beautiful even with timed entry restrictions introduced in 2022. Koh Lipe, the southernmost Thai island accessible by ferry from Pak Bara pier, has some of the clearest water and most pristine coral in the country but costs more and takes longer to reach. The Similan Islands and Surin Islands are accessible only by liveaboard dive trips or day boats from Khao Lak - closed May–October - and contain some of Southeast Asia's finest diving.

Ready-made plans

Thailand Itineraries

The classic Thailand first-trip circuit - Bangkok (3 nights), Chiang Mai (2–3 nights), then south to a beach destination (3–5 nights) - covers the country's three core experiences in 10–12 days. Bangkok to Chiang Mai is best done by flight (1 hour, under $40 booked ahead) rather than overnight train if time is limited; the train is a beautiful experience but costs 12–14 hours. The beach decision is the one that requires the most research: for November–April travel, the Andaman coast (Koh Lanta, Krabi, Koh Lipe) is the better choice; for May–October, the Gulf coast (Koh Phangan, Koh Tao) has better conditions.

For longer trips or return visitors: a Chiang Rai loop covering the White Temple, the Golden Triangle, and the border region takes 3–4 days from Chiang Mai. A Mekong river itinerary through Nong Khai, That Phanom, and Nakhon Phanom in Isaan is one of the most rewarding and least-travelled routes in the country. A full southern Thailand island-hopping circuit - Koh Phangan, Koh Tao, Koh Samui, ferry to Koh Lanta, Koh Phi Phi, Phuket - works well as a 3-week trip if you accept that it's mostly about beaches and snorkelling. We also have themed itineraries: temples and history only, food tourism (Bangkok + Chiang Mai + Isaan), diving circuits, and budget Thailand at $30 per day.

Activities

Things to Do in Thailand

Elephant sanctuaries have become Thailand's most ethically complex activity category, and navigating them well requires some research. Avoid any venue where elephants are ridden, paint, or perform - these are signs of training methods incompatible with welfare standards. Ethical sanctuaries, particularly around Chiang Mai (Elephant Nature Park being the most reputable), offer half-day and full-day programmes where you feed, bathe, and walk with retired working elephants in environments focused on rehabilitation. Book direct with the sanctuaries rather than through hotel desks that take commissions. A genuine ethical sanctuary visit is one of Thailand's finest experiences; a badly chosen one funds animal abuse.

Beyond elephants: a traditional Thai massage in Chiang Mai (1 hour, 200–400 THB at reputable massage schools on the old city moat) is one of the best-value experiences in travel anywhere. Muay Thai training camps accept foreign students for week-long courses at facilities in Chiang Mai, Bangkok, and Koh Phangan - a serious martial arts and fitness experience. Scuba diving on Koh Tao (one of the world's cheapest places to get PADI certified, around $300 for an Open Water course), snorkelling on the Similan Islands liveaboards, kayaking through the limestone karst sea caves around Phang Nga Bay (best at high tide when paddling inside the hongs, or lagoons, is possible). The Yi Peng lantern festival in Chiang Mai (November full moon, alongside Loi Krathong) - when thousands of paper lanterns drift upward above the old city - is one of Asia's most spectacular annual events.

Eat & Drink

Food & Drink in Thailand

Thai food is one of the world's great cuisines and is best understood through its five elements: salty (fish sauce, oyster sauce), sour (lime, tamarind), sweet (palm sugar), bitter (certain vegetables and herbs), and spicy (fresh chillies, roasted dried chillies). A well-executed Thai dish balances all five simultaneously - this is what separates great Thai cooking from merely competent versions of the same dishes. The challenge for visitors is that most tourist-oriented restaurants dampen the spice and reduce the complexity to appeal to international palates; eating at local markets and shophouse restaurants produces the real thing.

Bangkok's street food scene is legendary for a reason. Raan Jay Fai on Maha Chai Road - a street stall that has held a Michelin star since 2018 - charges $25–30 for crab omelette and is booked weeks ahead. But the best Bangkok street food experience isn't a single famous stall; it's walking Chinatown's Yaowarat Road at 9pm, or eating boat noodles at a riverside shophouse in Bang Rak, or having grilled skewers and papaya salad at a corner stall in On Nut at midnight. The principle: follow the queues of local workers during lunch, avoid anywhere with pictures of food plastered on the windows near tourist sights.

Regional specialities reward exploration. Chiang Mai's khao soi - rich coconut curry broth with egg noodles, topped with crispy fried noodles and pickled mustard greens - is one of the best dishes in Asia and should be eaten three times across two days to understand the range of good versions. Isaan's laab (minced meat salad with toasted rice powder, lime, and fish sauce) and sai krog Isaan (fermented Isaan sausage) represent a completely different culinary tradition from Bangkok. Southern Thai Muslim cuisine, found in Surat Thani, Nakhon Si Thammarat, and the deep south, uses more turmeric and coconut, with dishes like gaeng som (sour fish curry) and khanom jeen (rice noodles with fish curry sauce) that bear little resemblance to Bangkok's central Thai cooking.

Accommodation

Where to Stay in Thailand

Thailand is one of the world's best-value luxury destinations. The Aman at Phuket, the Four Seasons Koh Samui, the Rosewood Bangkok, the Mandarin Oriental Bangkok (one of Asia's great hotels, opened 1876, with river views and a spa in a converted colonial building) - these match or exceed the finest properties in Europe and the Maldives at roughly 60–70% of the price. The mid-range sweet spot - air-conditioned room, pool, breakfast - runs $40–80 per night at consistently high quality across the country. The guesthouse and hostel market (Chiang Mai's Old City, Bangkok's Banglamphu/Khao San Road area, any island's beach road) can produce genuinely excellent and atmospheric stays at $10–20 per night.

Where you stay changes the experience significantly. In Bangkok, Sukhumvit places you in the modern commercial city - good BTS access, malls, international restaurants. Silom is more local and slightly older, close to the night markets and Lumphini Park. The Riverside (Charoen Krung, Talat Noi) is the most atmospheric neighbourhood for heritage Bangkok, close to Chinatown and some of the city's most interesting new restaurants. For islands: beachfront bungalows (bamboo huts with sea views and outdoor showers) are the authentic backpacker choice on Koh Phangan and Koh Chang; budget $15–35 per night and accept that wifi will be poor and aircon rare. Boutique beach resorts in this price range ($60–120 per night) are found on Koh Lanta, Koh Lipe, and the quieter parts of Koh Phangan. Our accommodation guides cover specific hotels, guesthouses, and neighbourhoods at every budget level.

Logistics

Practical Information

Thailand uses the Thai Baht (THB). Cash is the primary currency for street food, local transport, market shopping, and guesthouses. ATMs (widely available everywhere) charge 220–300 THB per withdrawal from international cards, making fewer larger withdrawals more efficient. The current legal cashback withdrawal limit at most Thai ATMs is 20,000 THB per transaction. Cards are accepted at hotels, shopping malls, restaurants, and tourist sites in tourist areas. Avoid exchanging currency at airports (poor rates) or in the UK/Europe before travel (also poor rates); exchange offices in Bangkok's Silom or Pratunam, or SuperRich Exchange, offer significantly better rates than banks.

Getting a Thai SIM card is simple and cheap. AIS (best network for the north), DTAC, and True Move all sell tourist SIMs at Suvarnabhumi airport arrivals hall and at 7-Eleven stores throughout the country. A 30-day unlimited data SIM costs 299–599 THB. Alternatively, eSIM from Airalo or Holafly works at comparable prices without the airport queue. Bangkok's Grab app (Southeast Asia's Uber equivalent) is essential for city transport - use it over tuk-tuks and metered taxis where possible, as fare negotiation drains energy and frequently goes badly for visitors unfamiliar with the going rate.

Cultural respect is taken seriously in Thailand. Temples require removing shoes and covering shoulders and knees (both men and women). Never touch a monk or hand anything directly to a monk if you are a woman. The monarchy is protected by strict lèse-majesté law - any negative comment about the King, Queen, or their images is a criminal offence that has resulted in prison sentences for foreigners. Keep opinions about the monarchy entirely private. Heads are considered sacred (don't touch anyone on the head, even children); feet are considered low (don't point your feet at a Buddha image or a person, especially not while resting). These are not tourist traps - they are genuine cultural norms that Thais appreciate visitors respecting.

Context

Thailand: History and Culture in Brief

Thailand is one of the few nations in Southeast Asia that was never formally colonised by a European power - a fact of enormous national pride and historical significance. While Burma, Indochina, and the Malay Peninsula fell to British and French expansion in the 19th century, the Thai kingdoms navigated colonial pressure through a combination of diplomatic skill, strategic modernisation, and the advantage of their geographic position as a buffer state between British Burma/Malaya and French Indochina. King Chulalongkorn (Rama V, reigned 1868–1910) is particularly revered for this - his programme of modernisation preserved Thai sovereignty by adopting Western administrative and technological systems while resisting formal annexation.

The story of Thailand before the colonial era centres on the succession of Thai kingdoms that built the country's temple culture. The Sukhothai Kingdom (1238–1438), often considered the first unified Thai state, produced the distinctive Sukhothai Buddha style - elongated, flame-topped, and serene - and some of Thailand's finest temple architecture. The Ayutthaya Kingdom (1351–1767) became one of the most prosperous trading states in Asia, with Dutch, Portuguese, Chinese, and Japanese merchant communities operating in the capital; the city was destroyed by Burmese invasion in 1767 and the ruins of its temples remain one of Thailand's most moving historical sites. The Rattanakosin Kingdom, founded in Bangkok in 1782 by King Rama I, continues today - the current monarch, King Vajiralongkorn (Rama X), is the tenth ruler of the Chakri dynasty.

Theravada Buddhism is the religious and cultural foundation of Thai life in a way that penetrates far deeper than Western Christianity penetrates most Western societies. Over 90% of Thailand's population practises Buddhism; there are approximately 40,000 temples in the country; monks in saffron robes collect alms at dawn in every town and village; the Buddhist concept of merit (bun) - accumulated through giving, ethical action, and meditation - shapes social behaviour, generosity, and the hospitality towards strangers that Thailand is famous for. The Buddhist cosmology is visible everywhere: spirit houses at every building entrance, jasmine garlands on dashboards, golden Buddha amulets worn by almost everyone.

The 20th century brought Thailand into Cold War politics in ways that shaped its contemporary character. Thailand allied with the US during the Vietnam War, allowing American military bases on Thai soil and receiving substantial economic and military aid. The resulting influx of American soldiers created the foundation of the sex tourism industry in Pattaya and Bangkok's Patpong district - an industry that remains controversial and visible today, though it has been significantly regulated since the 1990s. Thailand's post-war economy developed rapidly through export manufacturing and tourism; the country joined the ranks of middle-income nations by the 1990s.

Contemporary Thailand is a constitutional monarchy with a parliament, but the military has staged numerous coups since 1932 (including the most recent in 2014) and the political situation remains complex. For visitors, this context is worth understanding without letting it dominate the experience - Thailand's temples, food, landscapes, and people are as extraordinary as they have ever been, and the vast majority of the country's political tensions are entirely invisible to tourists visiting the main destinations.

Thailand Travel FAQ

Do I need a visa for Thailand?
Citizens of most Western countries (US, UK, EU, Canada, Australia, New Zealand) can enter Thailand visa-free for 30 days since 15 September 2026, replacing the 60-day scheme of 2024; South Korean passports get 90 days. You receive a stamp on arrival at most major entry points. This can be extended once at an immigration office for a further 30 days (2,900 THB fee). Those planning longer stays can apply for a Thailand Long-Term Resident Visa or the SMART Visa. Passport must have at least 6 months validity remaining on arrival. Border runs to neighbouring countries (Laos, Cambodia, Malaysia) to reset the visa are still used by long-term travellers but have been tightened in recent years.
What is the best time to visit Thailand?
Thailand has three seasons: cool and dry (November–February, best time overall), hot and humid (March–June, before the rains), and monsoon (July–October, heavy rain particularly in the south and east). The cool season is the most comfortable for sightseeing, beach time, and trekking. The Gulf Coast (Koh Samui, Koh Phangan, Hua Hin) has its heaviest rains from October–December, meaning the Andaman Coast (Phuket, Krabi, Koh Lanta) is preferable in those months. The Andaman Coast gets its heavy rain May–October. Chiang Mai and the north are best November–February for cool temperatures and clear air; the burning season (March–April) brings serious smoke pollution to the north.
How much does a trip to Thailand cost?
Thailand remains exceptional value. Budget travellers (guesthouses, street food, local transport) can live very well on $25–40 USD per day. A comfortable mid-range trip - air-conditioned hotel, restaurant meals, day trips and activities - runs $60–120 per day. Luxury travel in Thailand - five-star resorts in Phuket or Samui, Michelin-starred dining in Bangkok - can be expensive on international terms but still undercuts equivalent European or US pricing. The most expensive part of any Thailand trip is almost invariably the international flight; once there, the country is remarkably affordable even by Southeast Asian standards.
Is Thailand safe for tourists?
Thailand is very safe for tourists and receives over 35 million international visitors per year. The main risks are practical: motorbike accidents (the leading cause of tourist injury and death), rip currents at beaches without lifeguards (Koh Tao, Koh Phangan, some Phuket beaches can have strong currents), and scams in major tourist areas - particularly the gem scam and the closed temple scam (a friendly stranger tells you a temple is closed and offers to take you somewhere "special"). Bangkok's tourist areas are safe to walk at night. The Deep South provinces (Pattani, Yala, Narathiwat, Songkhla) have an ongoing insurgency and are not recommended for tourists - the rest of the country is unaffected.
What food must I eat in Thailand?
Pad thai - flat rice noodles with egg, tamarind, and dried shrimp - is the entry point but far from the best thing on the menu. Tom yum goong (hot and sour prawn soup) made with fresh lemongrass and galangal is incomparable when made well. Som tum (green papaya salad, often eaten with sticky rice and grilled chicken) is the northern and northeastern staple. Massaman curry - a southern Muslim-influenced curry of potato, peanut, and spice that has been ranked the world's best food multiple times - deserves serious attention. Khao soi (Chiang Mai's signature dish: egg noodles in a rich coconut curry broth topped with crispy noodles) is a revelation. And Bangkok's street food at 11pm, when the real vendors set up around Chinatown's Yaowarat Road, is one of the great eating experiences in Asia.
Which is the best island in Thailand?
It depends on what you want. Koh Lanta (Andaman coast, November–April) is the most balanced island - good beaches, low-key atmosphere, excellent food, family-friendly, without Phuket's scale or Ko Samui's overdevelopment. Koh Lipe, in the deep south near the Malaysian border, has the most spectacular clear water and coral reefs in Thailand but is expensive and hard to reach. Koh Phangan outside Full Moon Party weekend has beautiful northern beaches and a more bohemian atmosphere than Koh Samui. Koh Chang in the east (Gulf coast, rainy season October–January) is large, mountainous, and much less visited than the southern islands. Similan Islands offer the best diving in the country but can only be visited by liveaboard or day trip from Khao Lak.
Is Bangkok worth visiting?
Bangkok is one of the great cities of Asia and absolutely worth multiple visits. The temples - Wat Phra Kaew (Temple of the Emerald Buddha), Wat Pho (reclining Buddha, and the best traditional massage school in the country), Wat Arun (the riverside Temple of Dawn, best viewed at dusk from across the Chao Phraya) - alone justify two full days. Chatuchak Weekend Market (8,000+ stalls, open Saturday and Sunday) is the largest weekend market in the world. Bangkok's restaurant scene has two Michelin-starred restaurants in its top tier (Gaggan, Le Normandie, Nahm are internationally recognised) and a street food culture that rewards wandering. The rooftop bar scene - Vertigo at Banyan Tree, Lebua at State Tower, Octave at Marriott Sukhumvit - is some of the finest in the world.
What are Thailand's most underrated destinations?
Chiang Rai is the most underrated city in the country - the White Temple (Wat Rong Khun), the Blue Temple, the Golden Triangle opium museum, and a food scene that is arguably better than Chiang Mai's in a city with a fraction of the crowds. The Sukhothai Historical Park - the ruins of Thailand's first kingdom, spread over 70 square kilometres and best explored by bicycle at dawn - is one of Southeast Asia's finest archaeological sites and barely visited compared to Ayutthaya. The Three Pagodas Pass on the Myanmar border in Kanchanaburi province provides a gateway to one of Thailand's most historically poignant landscapes (Death Railway, Hellfire Pass). Nan province in the far north has Lanna-era temples, mountain villages, and a cycling culture that is the antithesis of the Koh Samui experience.
How do I get around Thailand?
Bangkok's BTS Skytrain and MRT metro are fast, cheap, and air-conditioned - the most practical way to move around the city. For intercity travel: trains from Hua Lamphong station serve Chiang Mai (overnight sleeper, 12–13 hours, book weeks ahead), Ayutthaya (90 minutes), and Surat Thani (for Gulf islands). Buses are comprehensive and cheap - Air-conditioned VIP buses between Bangkok and Chiang Mai (9 hours) or southern destinations cost $10–20. Internal flights on Thai Airways, Bangkok Airways, and AirAsia are cheap to Chiang Mai, Phuket, Koh Samui, and other major destinations - usually $20–60 with advance booking. Island hopping uses ferries operated by Lomprayah and Seatran from Chumphon or Surat Thani piers.
What is Muay Thai and how do I watch it in Thailand?
Muay Thai (Thai boxing, or "the art of eight limbs" for its use of fists, elbows, knees, and feet) is Thailand's national sport and one of the most effective striking martial arts in the world. The best venues for watching authentic Muay Thai: Rajadamnern Stadium in Bangkok (Monday, Wednesday, Thursday, Sunday) and Lumpinee Stadium (Tuesday, Friday, Saturday) are the two major Bangkok venues; Rajadamnern has more atmosphere. In Chiang Mai, Thaphae Boxing Stadium hosts fights most evenings. In tourist areas like Koh Samui, Patong in Phuket, and Koh Phangan, fights are put on specifically for tourists and feature lower-level fighters; still worth attending for an introduction but not representative of the sport at its best.
