Siem Reap, the gateway to Angkor, lies about 150 km beyond the Thai border at Aranyaprathet–Poipet. Overland from Bangkok there are two approaches: a single international bus that takes you all the way, or getting yourself to the border, crossing on foot, and finding onward transport on the Cambodian side.

• Direct bus tickets Bangkok–Siem Reap: open 12Go

Option 1: Direct bus, Bangkok → Siem Reap

Several companies run through-services. Passengers get off to clear immigration and rejoin the same bus (or a waiting bus on the Cambodian side). Total time is about 8–10 hours including the border.

• Pros: no hunting for onward transport and no haggling in Poipet, which is where travelers are most often overcharged.
• Cons: few departures (mostly morning), and if one passenger is slow at immigration, everyone waits.

Option 2: Train or minivan to Aranyaprathet, then cross yourself

1. Bangkok → Aranyaprathet. A morning train from Krung Thep Aphiwat (5–6 hours, very cheap) or a minivan/bus from Mo Chit 2 (4–5 hours).
2. Station or bus stop → border. A shared truck or tuk-tuk, 10–15 minutes, to Rong Kluea market, which sits next to the crossing.
3. Cross. Thai exit stamp, walk across, Cambodian entry.
4. Poipet → Siem Reap. Buses, minivans and taxis, 2–3 hours.

• Pros: cheaper, and you choose your times (especially with the morning train).
• Cons: touts at the border, and finding onward transport in Poipet yourself.

Documents and the border

• Passport valid for at least six months.
• Cambodian visa. Most nationalities need one. An e-Visa applied for online before you travel is the smoothest; a visa on arrival is issued at the border but is where "helpers" appear. Nationals of ASEAN countries generally enter without a visa. Rules change — check the Cambodian government's current requirements before you go.
• Common traps: being led to a "visa office" before the real border, or offered form-filling for a fee. Walk directly to the official immigration buildings; the e-Visa needs no help at all.
• Mornings and Thai long weekends bring long queues — allow one to two hours at the border.

In Siem Reap

• Angkor tickets are sold at the official ticket centre outside town or online, as one-day, three-day and seven-day passes.
• Sunrise tours of Angkor Wat and a tuk-tuk with driver for the day are the most popular things to book in advance.

Which one for you

• First time, travelling as a group, lots of luggage → direct bus
• Tight budget, like flexibility, have crossed land borders before → train to Aranyaprathet and cross yourself
