To have a smooth and enjoyable trip to Thailand, pack light, breathable clothing and comfortable slip-on shoes, and be mindful of temple etiquette by dressing modestly and removing shoes when entering. Stay safe by being aware of scams, practicing food and drink safety, and taking precautions against mosquito bites, and ensure you have valid travel and medical insurance.

Before You Go:

Visa and Passport:

Ensure your passport is valid for at least six months beyond your intended stay and keep your immigration arrival/departure card safe.
Insurance:

Obtain comprehensive travel and medical insurance.
Vaccinations:

Consult with your doctor or a travel clinic about recommended vaccinations for Thailand.
Thailand Digital Arrival Card (TDAC):

As of May 1, 2025, non-Thai nationals entering Thailand must complete the TDAC online before arrival.

Packing Essentials:

Clothing: Lightweight and breathable clothing, especially for hot and humid weather.
Footwear: Comfortable walking shoes and easily removable slip-on shoes for temple visits.
Accessories: A sarong or shawl (versatile for beach and temple visits), mosquito repellent, and sunscreen.
Electronics: A universal adapter and portable charger.
Health: A small first-aid kit with basic supplies and any personal medications.

During Your Trip:

Money & Budgeting:

Thailand uses the Thai Baht. Carry some cash for smaller purchases, but credit cards are accepted in many places. Be aware that costs can be higher in popular areas and during peak season.
Health & Safety:

Drink bottled water and avoid tap water. Be vigilant about drink spiking and avoid leaving your drinks unattended. Use reliable mosquito repellent.
Cultural Etiquette:
Greetings: Return the "wai" (a prayer-like gesture with a bow) when offered.

Temples & Homes: Remove your shoes before entering temples, homes, and some shops or cafes.

Respect: Dress modestly when visiting religious sites and show respect to the monarchy. Avoid pointing your feet or resting them on tables or chairs, and never point your feet at people or statues.
Transportation:

Explore public transportation options like buses in cities for cost savings and convenience.
Scams:

Be cautious of scams and deals that seem too good to be true. Stick to reputable tour operators.
Responsible Tourism:

Avoid purchasing items made from endangered species or participating in activities that exploit animals.
