Which option to choose
| Option | Duration | For whom |
|---|---|---|
| Direct flight or with a stop | about 1 h 20 direct | Most travellers; the only reliable choice while the border is closed |
| Direct bus via Aranyaprathet-Poipet | 12 to 15 h formerly | Unavailable while the border is closed |
| Train Bangkok-Aranyaprathet then walking across and bus | long, over 15 h in all formerly | Unavailable while the border is closed |
Flights vary by season: compare airlines on the day you book. The airports are described in our guide to Bangkok airports.
The road route (if the border reopens)
Direct buses used to leave Mo Chit for Phnom Penh via Poipet, and a third-class train (about 50 THB according to a guide) ran to Aranyaprathet, going no further than the border. After Poipet, a bus or minivan goes to Phnom Penh. Do not book anything by road without recent confirmation. Beware of agencies at the border selling a fake, overpriced "visa" (see scams and safety in Bangkok).
Visa and formalities
Cambodia requires a visa for most nationalities, often obtained online (e-visa) before departure: check the fee and timing on the Cambodian government's official site. For your return to Thailand, see visa and entry to Thailand, as land entries are limited each year.
