Why travel in Thailand?

Few countries welcome visitors like Thailand does. From north to south, Thailand is full of timeless beauty. The golden temples of Ayutthaya tell stories of ancient kingdoms, while the lively floating markets remind you that local life still flows with the river.

Common Travelling in Thailand FAQs

Entry & Visas

One of the first questions is: Do I need a visa to enter Thailand? 

The answer depends on your nationality and how long you plan to stay. According to the official travel website of the Tourism Authority of Thailand (TAT), here are key points:

• Your passport should be valid for at least six months beyond your arrival date.
• Many nationalities can enter under a visa-exemption scheme for 30-60 days (depending on nationality).
• If you plan a longer stay, you may need a tourist visa or other type of visa—so check ahead.

Arrival & Immigration

From 1 May 2025, all foreign tourists arriving in Thailand (air, land or sea) must complete the digital arrival card, the Thailand Digital Arrival Card (TDAC). In 2025, the process is modernizing! Instead of filling in a paper arrival card on the plane, the TDAC must be submitted online in advance (or at a kiosk) for all non-Thai nationals and the key things to know are:

• You can submit the TDAC up to 72 hours before arrival.
• It covers your passport details, your flight or travel date, your address in Thailand, and some health-declaration questions.
• If you are transiting only (without passing through immigration) you might be exempt — check the rules. Completing this in advance helps make your entry into Thailand smoother, reduces delays and avoids confusion.

Payments in Thailand

Understanding the different payment methods can save you time and avoid some payment issues. Let’s explore each in detail:

• Thailand's currency is Thai Baht (THB). Credit and debit cards are widely accepted in major hotels, malls, restaurants – but cash is still used in many markets, street stalls and more rural areas.
• Always carry some cash for convenience, as small vendors or local transport may not take cards.
• Costs vary a lot by region: staying in Bangkok or on a premium island will cost more than in a smaller town. It’s wise to budget accordingly.
• Be aware of exchange rates and ATM fees.
• Many restaurants, shops, and even local vendors display their PromptPay QR codes to receive payments securely. The process are part of the national infrastructure (Bank of Thailand: BOT) digital-QR payments system. Thai citizens or residents who have a Thai-bank account via participating banks automatically have access to PromptPay through their mobile banking apps. 

Tips: Tourists or short-term visitors without a Thai bank account have limited access to using PromptPay directly. However: There are now services that allow foreigners to use QR payments linking to PromptPay codes by stepping through a tourist-specific prepaid e-wallet like TAGTHAi Easy Pay

Transportation & Getting Around

Thailand’s transport system is good and varied. You have many options like flights, trains, buses, ferries, taxis, ride-hailing apps and local shared transport (Song Theaw).

• Domestic flights are plentiful and affordable between major cities and islands.
• Buses and coaches connect many towns and provinces.
• Trains operate in many regions but may be slower.
• In cities, use official taxis (preferably with meter) or ride-hailing apps to avoid confusion.
• For islands, boats and ferries are essential and there are many local services. Please check the schedules and prices before you make any accommodation booking

Tips:  Always check local weather conditions (which can affect ferry schedules, mountain roads, etc)

Accommodation

From luxury resorts to budget guesthouses, Thailand has many accommodation options.

• In big tourist hubs you’ll find high-end hotels with full services.
• In smaller towns you can stay in boutique guesthouses, homestays or eco-lodges.
• Booking ahead is wise for high-season travel (e.g., major festivals, island holidays).
• Check the location relative to the things you want to do so you can minimize travel time.
  
  Tips: Do not forget to read reviews, check cancellation policies, and review other regulations such as additional fees or taxes that may apply (like resort fees, service charges, etc.).

Safety & Travel Insurance

Safety is always a key concern for tourist. The majority of visits to Thailand are trouble-free. But you should still take sensible precautions:

• Make sure you have travel insurance that covers you while overseas (illness, accidents, theft).
• Check if any vaccinations or health measures are recommended for the region you plan to visit.
• Road safety: If you rent a scooter or motorbike, you must know the rules, wear a helmet and ride carefully. Some accidents happen with tourists who are unfamiliar with local roads.
• Be aware of local laws and customs. For example, drug laws in Thailand are strict and ignorance is not always accepted.
• Petty scams may happen in tourist areas. If possible, always use meter taxis, agree price beforehand when ride-sharing or doing unusual tours, and be cautious of offers that seem too good to be true.

Culture & Etiquette

Visiting Thailand also means experiencing Thai culture, so being respectful goes a long way. Following local customs helps you feel more comfortable and builds good relations with people you meet.

• Learn a few basic Thai words such as “Sawadee” (hello), “Khob khun” (thank you).
• Dress modestly when visiting temples or sacred sites: shoulders and knees should be covered.
• Remove your shoes when entering a home or temple building.
• It’s polite to show respect to images of the King. Criticism of the monarchy is a serious matter in Thailand.
• Tipping is not required but is appreciated, especially if service is good.

Best Time to Visit

Choosing the right time to visit can make a big difference to your experience. With a tropical climate, Thailand has 3 main seasons: hot, rainy and cool.

• The cool season (roughly November to early February) is generally considered the best time for many destinations.
• The rainy season in Thailand usually runs from May to October, depending on the area. Even though it can rain heavily at times, it’s also a great time to visit with fewer tourists and more affordable prices.
• Keep in mind that remote islands and mountain areas may have slightly different conditions. Please check local weather forecasts. 

Responsible Travel & Respecting the Environment

As more tourists visit Thailand, being a responsible visitor matters.

• Support local businesses and artisans, instead of large chain stores, the smaller ones may benefit more.
• Be mindful of wildlife tourism: make sure animal interactions are ethical and respectful.
• Avoid littering and help keep beaches, parks and forest areas clean.
• Learn about “Leave No Trace” principles and local conservation efforts. Your presence as a tourist should help protect, not harm, the places you visit.
