 Crucial Safety Note: All international governments – including the US, UK, Canada, and Australia – currently advise their citizens to avoid all travel within 50 km of the Thailand-Cambodia land border due to armed conflict, landmines, and unpredictable security situations. Do not attempt to cross at unofficial points.

1. By Air (Fastest & Safest)

Flying is by far the best way to travel between Thailand and Cambodia in 2026. It is safe, reliable, and avoids all border complications.

Bangkok to Phnom Penh

Flights from Bangkok’s two airports – Suvarnabhumi (BKK) and Don Mueang (DMK) – land at Techo International Airport (KTI) , Phnom Penh’s new world‑class airport that opened in late 2025.

Typical fares: Economy class starts around THB 8,000–10,000 round trip, though budget carriers may offer promotional fares as low as THB 3,600 one‑way. Advance booking is strongly recommended.

Bangkok to Siem Reap

Flights from Bangkok land at Siem Reap Angkor International Airport (SAI) , the modern gateway to Angkor Wat.

As of April 2026, there are approximately 35 flights per day operating between Bangkok and Siem Reap. The most popular departure time is 5:00 PM, with about 55% of flights leaving in the afternoon and evening.

Typical fares: One‑way tickets start around THB 3,200, with round‑trip fares varying by season and booking time.

Other Routes

• Chiang Mai to Siem Reap: Limited direct flights available via Bangkok Airways and Cambodia Angkor Air.
• Phuket to Phnom Penh: Seasonal direct flights; most routes connect through Bangkok.

2. By Land: The New Direct Bus Service

This is big news for budget travelers. In April 2026, Thailand’s state‑owned Transport Co. launched brand‑new direct bus services from Bangkok to Phnom Penh and Siem Ream – the first direct bus connections since the pandemic.

Bangkok to Phnom Penh

The route uses air‑conditioned buses operated in partnership with Vireak Buntham Express Co. , a well‑known Cambodian transport company.

What to Expect on the Bus Journey

• Border procedures: The bus will stop at the border for passport control. Expect the process to take 1–2 hours depending on queue length.
• Total travel time: Including border formalities, plan for 7–9 hours of actual travel plus waiting time.
• Comfort: Air‑conditioned coaches with reclining seats. Bring snacks, water, and entertainment.

 Important: These buses cross the border legally through designated checkpoints. However, they still pass within the 50 km zone that many governments advise avoiding. International travelers should check their home country’s latest travel advisories before booking.

Traditional Overland Options (Limited)

Prior to the conflict, travelers could cross at several land border points. In 2026, most remain closed or heavily restricted:

Border Crossing	Status	Notes
Poipet / Aranyaprathet	Partially open with restrictions	Thai nationals prohibited from crossing; reduced hours (8 AM – 4 PM)
Nong Ian / Stung Bot	Open	New permanent crossing at Thai-Cambodian Friendship Bridge, operating 6 AM – 10 PM daily
Chong Sa-ngam / Anlong Veng	Restricted	Extended hours (7 AM – 10 PM) but subject to security checks
Other crossings	Closed	All other land border points remain closed

Shared minivans and private taxis are theoretically available from Bangkok to the border, but given the restrictions and government warnings, the direct bus service is strongly recommended over arranging your own overland crossing.

3. By Sea

There are no operational passenger ferry services between Thailand and Cambodia in 2026. While cruise ships occasionally stop at Sihanoukville, there are no regular sea connections for independent travelers.

Visa Requirements

Entering Cambodia

Most nationalities require a visa to enter Cambodia. Options include:

Visa on Arrival is available at Phnom Penh’s Techo Airport (KTI) and Siem Reap Airport (SAI). E‑visa can be applied online at the official government website.

 New requirement: All travelers must complete an electronic Arrival Card (e‑Arrival) before arrival, either via the official website (www.arrival.gov.kh) or the Cambodia e‑Arrival mobile app, up to 7 days in advance.

Entering Thailand

Most nationalities can enter Thailand visa‑free for up to 30 days (by air) or 15 days (by land). Extensions and other visa types are available at Thai immigration offices.

Critical Safety Advisories

Do not attempt to cross the Thailand-Cambodia border at unofficial points. Multiple governments have issued strict warnings:

 Key takeaway: If you are already in Thailand and wish to visit Cambodia, fly. Do not attempt to drive or take a taxi to the border unless using the official new bus service, which handles border procedures professionally.

Getting Around Once You Arrive

Once you land in Cambodia, use these trusted services:

• Tuk‑tuk / taxi: Use PassApp or Grab apps for fixed prices and driver tracking.
• Scooter rental: $6–10/day (experienced riders only).
• Private driver: Arrange through your hotel or reputable agencies.

For Phnom Penh arrivals, the new Techo International Airport (KTI) is located approximately 20 km south of the city center. A tuk‑tuk to the city costs $7–10 via PassApp.
