🛂 1. Visa & Latest Entry Requirements (2026)
Preparing for your Thailand trip starts with understanding the latest entry requirements. Thailand offers friendly policies for international tourists, but digital verification steps have been updated.
- Visa-Free Entry: Many nationalities enjoy visa-free entry to Thailand, allowing stays of up to 60 days. This makes planning long vacations in Bangkok or Chiang Mai incredibly easy. Please check your passport's specific eligibility before flying.
- TDAC (Mandatory Digital Arrival Card): Thailand has fully implemented TDAC (Thailand Digital Arrival Card), replacing the old paper forms. You must fill it out on the official immigration website within 72 hours before your departure. Save a screenshot of the QR code to show customs.
- 300 THB Tourism Fee: Implemented in 2026, this fee is typically included in your airline ticket taxes if arriving by air. Those entering by land or sea must pay via the online system.
- Customs Check (Proof of Funds): Ensure your passport is valid for at least 6 months and have your return tickets and hotel bookings ready. Crucially, tourists entering under the visa exemption must carry cash equivalent to 20,000 THB per person (or 40,000 THB per family) as proof of funds. Though it's a random check, failing to show sufficient cash (USD, EUR, or your local currency is fine) can result in denied entry.
💵 2. Currency Exchange by City
Understanding local payment methods makes your trip much smoother. While locals rely heavily on PromptPay (QR codes), it is difficult for tourists to set up without a Thai bank account. Cash remains essential for street food, night markets, and small vendors.
Where to get the best exchange rates:
Bangkok
Exchange a small amount at your home country for airport transport. In the city, head to SuperRich (Green or Orange signs) for the absolute best rates. Bring crisp USD/EUR bills. Check SuperRich Rates online.
Chiang Mai
Look for SuperRich Chiang Mai (which operates independently from the Bangkok branches) or SK Exchange near the Old City gates. Both consistently offer the most competitive rates in northern Thailand.
Phuket
Avoid exchanging large sums at Phuket Airport. Head to Patong Beach or Phuket Town and look for Value Plus or independent exchange booths, comparing rates across a few stalls before committing.
Hat Yai
Due to border proximity, local money changers near Lee Gardens Plaza offer excellent rates, particularly for Malaysian Ringgit (MYR) and Singapore Dollars (SGD).
📱 3. Internet & SIM Cards
Thailand's top three telecom operators (AIS, TrueMove H, dtac) offer excellent signal coverage and 5G speeds, even on the islands. We highly recommend purchasing a Thailand Tourist eSIM online (via platforms like Klook or Trip.com) before departure. You can activate it the moment you land, skipping the long queues for real-name registration at airport kiosks.
🚗 4. Transportation Guide by City
Ride-hailing apps are essential in Thailand, but the ideal transportation method varies drastically depending on your destination.

Bangkok: Trains Over Cars
Bangkok traffic is notoriously congested. Rely heavily on the BTS (Skytrain) and MRT (Subway). Purchasing a Rabbit Card will save you from queuing for single-journey tickets. For ride-hailing, Grab and Bolt are widely used, but expect delays during rush hours.
Chiang Mai: Apps & Red Trucks
There is no subway system in Chiang Mai. Grab, Bolt, and Maxim are extremely reliable and affordable here. For a classic local experience, hop on a Songthaew (Red Truck)—just tell the driver your destination and negotiate the fare (usually starting at 30 THB) before boarding.
Phuket: Avoid Street Taxis
Local street taxis and Tuk-Tuks in Phuket are infamous for being expensive. Highly recommend using Bolt or InDrive for significantly cheaper and transparent fares. For coastal travel between beaches, the Phuket Smart Bus is a fantastic, budget-friendly option.
Hat Yai: Walkable & Tuk-Tuks
The downtown area (around Lee Gardens) is highly walkable. For longer distances, Grab is available. You can also easily flag down local Tuk-Tuks, but always agree on the price before getting in. Some drivers even accept Malaysian Ringgit due to the influx of weekend tourists.
👕 5. Weather & Temple Dress Codes
Thailand is hot year-round. Pack light, breathable summer clothes and strong sunscreen. However, indoor AC is often blasted on high, so carrying a light jacket is highly recommended.
⚠️ Strict Temple Dress Code
If you plan to visit the Grand Palace or famous temples (like Wat Arun in Bangkok or Doi Suthep in Chiang Mai), sleeveless tops, shorts, short skirts, ripped jeans, and flip-flops are strictly prohibited. You must wear tops with sleeves and pants/skirts that cover your knees, or you will be denied entry.
🚫 6. Absolute Taboos & What to Avoid
- E-Cigarettes are Banned: Thailand has a strict nationwide ban on vaping and e-cigarettes! Carrying or using them is illegal and can lead to hefty fines or even jail time. Do not risk it.
- Respect the Royal Family: Thai people deeply respect their Royal Family. Never criticize or make jokes about them in public. If a coin drops on the floor, never step on it to stop it from rolling (as it bears the King's image).
- Tipping Etiquette: Tipping is customary in Thailand (for hotel maids, massages, bellboys). Usually, 20-50 THB paper bills are given. Never tip with coins, as in local culture, coins are meant for beggars.
- Cannabis Laws: While cannabis has been decriminalized in Thailand, taking it out of the country or returning home with traces in your system is illegal in many jurisdictions. Understand the risks related to your home country's laws.
