What to Expect on the Bus Journey

⚠️ 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:
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.
