Traveling to Thailand Independently: Essential Items for a Perfect Trip

@jessicachaw | thailand travel entry requirements

If you want your independent trip to Thailand to go smoothly without unexpected situations, prepare some important items in advance. These tips will help you save time, optimize costs, and enjoy your trip more fully.

Exchange Thai Baht in Advance

One of the things to do before flying is to exchange some Thai Baht (THB) right in Vietnam. Although Thailand has many places to exchange money, having cash readily available upon arrival will make it more convenient for situations where you need to spend immediately.

If you’re only staying for 3-5 days, you can exchange around 3,000-5,000 THB to cover food, transportation, and small purchases. Larger payments such as hotel accommodations, entrance fees, and shopping at malls can usually be paid by credit card.

Where to exchange money?

In Vietnam: Major banks or reputable gold shops can exchange Thai Baht at better rates than at Thai airports.
In Thailand: If you need to exchange more, look for reputable currency exchange counters like SuperRich or banks. Avoid exchanging money at the airport as the exchange rate is usually lower.
If you don’t want to carry too much cash, you can withdraw money from ATMs in Thailand, but be aware that withdrawal fees range from 150-220 THB per transaction.

Purchase a Travel SIM or eSIM in Advance
