What should I know before visiting Thailand?

Direct answer

Thailand is a popular, generally safe destination with tropical weather, rich culture, and varied transport. Plan visa/entry, seasons, safety, customs, money, and transport ahead to enjoy beaches, cities, and temples smoothly.

Visa / entry requirements

• Visa exemption: Many nationalities (incl. US, EU, UK, Canada, Australia) get 30 days visa-free by air and 15 days by land; check your nationality. Extensions available at immigration.
• Tourist visa: Single-entry 60-day tourist visas can be obtained from Thai consulates. Visa-on-arrival is available for some nationalities for short stays (15 days).
• Passport: Must be valid for at least 6 months on arrival and have blank pages.
• Proof of onward travel: Airlines/immigration may ask for return/exit ticket and sufficient funds.
• COVID: Verify latest entry/health rules before travel (testing/vaccination requirements can change).

Best time to visit

• Cool/ dry season (Nov–Feb): Most comfortable across the country; peak tourist season.
• Hot season (Mar–May): Very hot, especially inland (Bangkok, Chiang Mai); island trips still popular.
• Rainy/ monsoon season (Jun–Oct): Fewer crowds, lower prices, heavy rains possible—best for lower costs and green landscapes.
• Regional variation: Southern islands differ—Gulf coast (Koh Samui) has different monsoon months than Andaman coast (Phuket, Krabi).

Safety tips

• Petty crime: Watch out for pickpockets in crowded areas and scams around major attractions.
• Scams: Common ones include tuk-tuk tours with high-pressure shopping stops, gem scams, and overly cheap tours. Book from reputable operators.
• Drugs: Very strict laws and severe penalties for possession or trafficking.
• Road safety: Traffic can be chaotic; be cautious when motorbiking—wear helmets and have adequate experience and insurance.
• Health: Stay hydrated, use sunscreen and insect repellent (dengue risk in some areas). Get routine vaccinations; consider travel insurance that covers medical evacuation.

Local customs & etiquette

• Respect the monarchy: Avoid disrespectful comments about the royal family—this is a serious offense.
• Wai greeting: A slight bow with palms together is customary—return it when offered.
• Temple etiquette: Dress modestly (shoulders and knees covered), remove shoes before entering temple buildings, speak quietly, and avoid pointing feet toward Buddha images.
• Public behavior: Avoid public displays of anger; touching someone’s head is impolite; pointing with finger is rude (use whole hand).
• Tipping: Not mandatory but appreciated—small tips for good service in restaurants, guides, and drivers are common.

Currency & money

• Currency: Thai Baht (THB).
• Cash: Widely used—carry cash for markets, taxis, and small vendors. ATMs are common in cities; fees apply.
• Cards: Credit/debit cards accepted in hotels, larger restaurants, and shops; notify your bank of travel to avoid blocks.
• Currency exchange: Better rates at banks or official exchange counters; avoid exchanging at airports if you want best rates, though airports are convenient.

Transportation

• Domestic flights: Fast and affordable between major hubs (Bangkok, Chiang Mai, Phuket, Krabi, Koh Samui).
• Trains: Comfortable overnight trains (Bangkok–Chiang Mai) and scenic routes; book ahead for sleepers.
• Buses & minivans: Extensive network; quality varies. VIP buses are more comfortable for long distances.
• Taxis & ride-hailing: Metered taxis in Bangkok (ensure meter is used). Grab app is widely used in cities.
• Tuk-tuks & motorbike taxis: Handy for short trips—negotiate price in advance for tuk-tuks if meter isn’t used.
• Ferries/boats: Essential for island hopping—check schedules and book ahead in high season.

Must-know tips & local insights

• SIM & connectivity: Buy a local SIM at airport or convenience stores for cheap data; eSIM options available for many nationalities.
• Power plugs: Type A, B, C, and O used; 220V supply. Bring a universal adapter.
• Bargaining: Expected at markets and street stalls—start lower and be polite. Do not haggle in fixed-price shops.
• Food & water: Street food is excellent; choose busy stalls with high turnover. Drink bottled water; avoid ice in remote areas if unsure of source.
• Culture & experiences: Don’t miss temples (Grand Palace, Wat Pho), northern culture in Chiang Mai, islands (Phuket, Krabi, Koh Phi Phi, Koh Samui), and local festivals (Songkran in April, Loy Krathong in Nov).
• Sustainable travel: Support local businesses, avoid single-use plastics, and be mindful of wildlife tourism (avoid attractions that exploit animals).

• Book accommodation and key transport during high season
• Buy travel insurance with medical coverage
• Get local currency or ATM card ready
