🇹🇭Thailand Travel Guide

Visa requirements for Thailand depend on your passport. Most US, UK, EU, Canadian, Australian, Japanese, and Singaporean citizens enter visa-free for tourism (typically 30–90 days). Pick your citizenship in the visa section above for exact rules.

Standard tourist stays in Thailand are 30 to 90 days depending on your nationality. Longer stays usually require an eVisa, residence permit, or — where available — a digital nomad visa.

A passport valid 6+ months beyond your stay, return or onward ticket, accommodation address, and proof of funds. Some nationalities also need an online travel authorization before boarding.

A mid-range traveler in Thailand spends about $90/day, so a 7-day trip is roughly $630 excluding flights. Budget travelers can do it for less, luxury travelers significantly more.

Thailand sits in the "Low" cost tier on TravelOS. Mid-range daily spend is around $90 including accommodation, meals, transport, and one paid activity.

The best time to visit Thailand is Nov–Feb — mild weather, fewer crowds, and lower prices than peak summer.

Thailand has distinct seasonal patterns. Check our country guide for month-by-month temperatures, rainfall, and what to pack so you can match dates to weather.

Thailand scores 78/100 on the TravelOS safety index. Main risks are petty theft in crowded tourist areas and standard road-safety. Always check your government's travel advisory before booking.

Solo female travelers regularly visit Thailand. Stick to well-reviewed accommodation, use licensed taxis or ride-hail apps after dark, and follow local dress norms in religious sites.

The capital of Thailand is Bangkok, which is also the main international gateway for most travelers.

Airalo and Holafly both offer Thailand eSIMs that activate in 90 seconds, so you have data the moment you land. See the eSIM section in our country guide for current plans and prices.

Yes. Major eSIM providers (Airalo, Holafly, Saily, Nomad) cover Thailand on the main local 4G/5G networks. You can install the eSIM before departure and it activates automatically once you land and your phone connects to a partner network.

Buy the plan online, scan the QR code from the confirmation email, install the eSIM profile in your phone settings, and toggle data roaming on the eSIM line. Most plans activate the first time the phone registers on a network in Thailand — usually within 90 seconds of landing.

Plans start around $13 for 10GB valid 30d on Airalo. Larger 10–20 GB plans usually cost $20–$40 and cover 2–4 weeks of travel.

eSIM works on iPhone XS and newer, Google Pixel 3 and newer, and most Samsung Galaxy S20+ devices. Phones must be carrier-unlocked. Some phones bought in mainland China and a few older Android models do not support eSIM — check your device settings for "Add eSIM" or "Mobile plan".

Almost always. International roaming with a home carrier usually costs $10–$15 per day; a travel eSIM is closer to $1–$2 per day for the same coverage. eSIMs also avoid surprise bills since they are prepaid.
