Important Travel Alert (April 2026)
As of late 2025 and continuing into 2026, all land border crossings between Thailand and Cambodia, including the Aranyaprathet–Poipet crossing, remain closed due to an ongoing military border dispute between the two countries. A ceasefire took effect on December 27, 2025, but the situation remains fragile. Currently, the only way to travel between Bangkok and Siem Reap is by air. Travelers are strongly advised to check the latest advisories from their home country’s foreign ministry before booking any travel to the Thailand-Cambodia border region.

Flights from Bangkok to Siem Reap – The most convenient way
Flying is the most convenient way to get from Bangkok to Siem Reap under normal circumstances, and as of April 2026, it is the only viable option given the closed land borders.
The flight takes approximately 1 hour and 15 minutes. Multiple airlines serve this route, including AirAsia (departing from Don Mueang Airport, DMK), Bangkok Airways, Thai Smile, and Cambodia Angkor Air. AirAsia is typically the most budget-friendly, with fares starting around $50 one-way plus checked luggage fees. Round-trip fares on low-cost carriers average around $100–$220 depending on how far in advance you book.
From Bangkok Center City to BKK Airport
Bangkok has two main airports. Don Mueang (DMK) handles most low-cost carriers like AirAsia, while Suvarnabhumi (BKK) serves full-service airlines.
- From city center to Suvarnabhumi (BKK): The Airport Rail Link from Phaya Thai or Makkasan stations takes about 30 minutes and costs around 45 Thai Baht ($1.50). Taxis cost 300-500 Baht ($10-$16) depending on traffic (30-60 minutes). Public buses (S1, S4) are cheapest at around 35 Baht but much slower.
- From city center to Don Mueang (DMK): Take the BTS to Mo Chit, then bus No. 29 or 59 to Don Mueang. A taxi costs around 200-350 Baht from central Bangkok.
From Siem Reap International Airport to Center City
Note: As of September 9, 2025, the new Siem Reap Angkor International Airport (SAI) has officially replaced the former airport as the main gateway to Angkor Wat. It is located about 50 km from the city center, so factor in longer transfer time.
- Taxis cost approximately $20-$35 to the city center (further than the old airport).
- Tuk-tuks can be arranged via apps or hotel concierge. Negotiate the price in advance.
- Some hotels offer shuttle services worth checking when you book.
Train to Siem Reap from Bangkok: The Fascinating Way
While there is no direct train service from Bangkok to Siem Reap, you can take a train to the border town of Aranyaprathet, and then continue the journey by bus or taxi to Siem Reap. The train ride itself offers a unique experience, showcasing the picturesque countryside of Thailand. Moreover, local food is also often bought on board.
There will be 2 journeys you need to pay attention to when taking the train:
Train to Aranyaprathet
Trains depart from Bangkok’s Hua Lamphong Station to Aranyaprathet. The journey takes around 5-6 hours, and the ticket prices range from 48 to 290 Thai Baht ($1.50-$9.50), depending on the class of travel.
From Aranyaprathet to Siem Reap
Upon reaching Aranyaprathet, you can take a shared taxi or a bus to the Thai-Cambodia border at Poipet. From there, you can arrange transportation to Siem Reap, which is approximately a 2-3 hour journey.
Important Note: Do not pay for transport upfront if taking unofficial taxis. Poipet has a notorious scam environment, stay on the main path to the transport depot and ignore anyone who approaches offering “help.”
Taking a Bus to Cross the Border – The Cheapest Way
When the Thailand–Cambodia land border is open, taking a direct bus is the most economical way to make this journey. The trip typically takes 8–10 hours and costs $15–$32 depending on the operator.
Buses depart from Bangkok’s Northern Bus Terminal (Mo Chit) or Eastern Bus Terminal (Ekkamai), both conveniently located near BTS Skytrain stations. Consider booking your tickets in advance, especially during peak travel seasons.
Several bus companies operate direct services between Bangkok and Siem Reap such as Giant Ibis and Nattakan, offering varying levels of comfort and price ranges. The direct buses eliminate the need to switch buses at the border, ensuring a hassle-free experience. Your luggage remains onboard while you handle the necessary visa formalities.
Visa Requirements at the Thailand – Cambodia Border
Before crossing into Cambodia whether by land or air, understand the entry requirements:
- E-Visa (recommended): Apply online at evisa.gov.kh before your trip. Costs $30 for a tourist visa plus a $6 handling fee. Processing takes 3 business days. Accepted at major airports and select land borders. For air arrivals, this is the smoothest option.
- Visa on Arrival: Available at airports and most land crossings. Tourist visa costs $30; business visa $35. Both are valid for 30 days, single entry. Bring a passport photo (otherwise a $2–5 fee applies) and USD cash in small denominations.
- ASEAN nationals (Thailand, Vietnam, Malaysia, Singapore, Indonesia, Philippines, Laos, Brunei) are visa-exempt for stays of 14-30 days.
- Passport validity: Your passport must be valid for at least 6 months beyond your entry date and have at least one blank page.
New in 2025–2026: The Cambodia V-Pass (E-Arrival Card)
All air travelers must now complete an electronic arrival card (V-Pass) at least 7 days before arrival via the official arrival.gov.kh website or app. This replaces the old paper forms and combines immigration, health, and customs declarations in one digital form. It’s free and takes about 10 minutes. Overland travelers still complete paper forms at the border.
Extra Tips at Thai-Cam Border
When crossing the border from Thailand to Cambodia, follow these tips to ensure a smooth and hassle-free experience:
- Do not change anything in the border (especially currency)
- The most common and popular border crossing between Thailand and Cambodia is the Aranyaprathet-Poipet border. It’s advisable to choose this border crossing for a smoother journey.
- Make sure to have enough cash in USD or Thai Baht to pay for the visa fee and any additional fees at the border.
- Do not take anything at the border from locals, anyone approaching you at Poipet offering to “help with your visa” or suggesting you follow them is likely running a scam. Proceed directly to the official immigration building.
- Border crossings can sometimes be time-consuming, especially during peak travel periods. Be patient, plan for delays, and allocate sufficient time for the border crossing process.
- Have all the necessary documents, including your passport, visa, and any supporting documents, ready for inspection. Fill out any required forms accurately and completely.
