Thailand Travel Tips

U.S. passport holders can typically enter Thailand visa-free for tourism for up to the standard permitted stay. Your passport must be valid for at least six months beyond arrival. Always confirm the latest rules before you fly — we send full guidance after booking.

The currency is the Thai Baht (THB). Carry some cash for markets, street food, and tips, but cards are widely accepted in cities and hotels. ATMs are everywhere; notify your bank before traveling to avoid holds. If you’re still comparing tour companies, our guide to choosing a Thailand tour operator covers what the headline price does and doesn’t include.

The cool, dry season (November–February) is the most popular and comfortable. March–May is hot; June–October is the green season with short tropical downpours and fewer crowds. Our peak departures align with the best weather.

Thailand’s most joyful festival, Songkran, rings in the Thai New Year every April 13–15 with nationwide, good-natured water fights to wash away the old year. It’s an unforgettable time to visit — wear quick-dry clothes, seal your phone and camera in a waterproof pouch, and expect to get happily soaked. Two of our April departures land right on Songkran — look for the festival badge on those dates.

Lightweight, breathable clothing, plus a layer for cool northern evenings. Bring modest attire for temples (covered shoulders and knees), comfortable walking shoes, sunscreen, insect repellent, and a reusable water bottle.

Remove shoes before entering temple buildings, dress respectfully, and never point your feet at Buddha images or touch a monk if you are a woman. Photography is usually fine outdoors but check for signs inside.

Thai food is one of the world's great cuisines — eat adventurously but choose busy, popular stalls. Drink bottled or filtered water, which is provided throughout our tours. Tell us about any allergies or dietary needs in advance.

Affordable tourist SIM cards and eSIMs are available at the airport with generous data. Wi-Fi is common in hotels and cafes. Our U.S. and in-country teams stay reachable throughout your trip.

No vaccinations are required for most travelers, but consult your doctor. Thailand is very welcoming and safe for tourists — use normal precautions and keep valuables secure.

Thais greet with a "wai" (palms together). The royal family is deeply respected. A smile goes a long way, losing your temper does not — patience and politeness are valued. Tipping is appreciated but not mandatory.
