Ja wenn man über PP fliegt aber da dauert die Reise genau so lange wie von BKK aus.
Es gibt eine Seite die das anbietet von BKK nach Ankor 4900 bath:

ist aber thailändisch müsst ihr dann mit übersetzer lesen
Also wenn man von BBK aus fahren will auf eigene Faust habe ich das gefunden:
Bangkok ► Siem Reap (Angkor) & Phnom Penh
Step 1, travel from Bangkok to Aranyaprathet by train, leaving Bangkok's main Hualamphong station at 05:55 every day and arriving Aranyaprathet 11:35. The fare is just 48 baht (about £1 or $1.60), no reservation necessary, simply turn up and buy a ticket at the station on the day (the ticket office will be open!). They may offer a combined train+bus ticket to Siem Reap, but I recommend only buying the train ticket, to stay flexible with onward transport. Bangkok to Aranyaprathet is 255 km, 159 miles. The train is 3rd class only, but it's clean, spacious and it's a pleasant and enjoyable ride, clickety clacking along with a breeze blowing through the open window. There's also a 13:05 train from Bangkok arriving Aranyaprathet at 17:35, but this is a bit too late to move on from the frontier and you may have to spend the night at Poipet. Useful tip: This train also calls at Phaya Thai station at 06:10 (next to the Phaya Thai BTS Skytrain station) and Makkasan station at 06:20 (Makkasan railway station is not the same as the Airport Rail Link's Makkasan station, make that clear to your taxi driver). Boarding at these stations can be more convenient if you're staying in northern Bangkok.
Step 2, take a tuk tuk from Aranyaprathet station to Poipet. Aranyaprathet is only 6 kilometres (3.8 miles) from the Cambodian border at Poipet, and you'll find tuk-tuks waiting for you at the station. Take a tuk-tuk from the station to Poiphet, cost 80-100 baht, journey time 10 minutes. If you haven't already bought a Cambodian e-visa, tuk-tuk drivers may try and take you to a travel agency to buy a Cambodian visa at inflated prices. This is no real problem, just say 'No' and insist that they take you direct to the border point and they will do so. They may tell you it's an 'official' visa office, and official-looking people may even ask to 'see' your passport or visa, just ignore them and repeat that you want to be taken to the official border post, and you'll be taken there. The official Cambodian visa office is after Thai exit formalities, between the Thai and Cambodian border posts. So it's really very simple: If you haven't had your passport stamped by a Thai border guard at the Thai border post and passed through the 'Angkor' arch (see the photos of these below), it ain't the official Cambodian visa office! The official visa cost is $20.
Step 3, walk across the border. The border is open 07:00-20:00, and Cambodian visas can be bought there if you haven't bought a Cambodian e-visa beforehand. First get your passport stamped at the Thai side, then walk on for 100 yards under the 'Angkor' 'Welcome to Cambodia' archway to the Cambodian border post to buy your Cambodian visa, have your fingerprints scanned and your passport stamped. Be careful with your valuables when crossing the border, just in case there are pickpockets around. The whole process should only take around 30 minutes, but at busy times it can take an hour, sometimes more.
At the exit from Poipet border post onto the big roundabout, you will see (or be guided to) an official free transit bus to the 'Poipet Tourist Passenger International Terminal' 10 minutes down the road from where all the share taxis and buses leave for Siem Reap or Battambang or Phnom Penh. This shuttle bus (and the man with the official badge who guides you to it) is legitimate.
Step 4, take a bus, minivan or share taxi from Poiphet to Siem Reap. This is 152 km (95 miles) and should take around 2½ hours by share taxi or 3 hours by bus now that the highway has been improved. Prices are posted at the ticket counter at the Poipet Tourist Passenger International Terminal. A shared taxi costs $12 for a seat or $48 for the whole car. A bus costs $9, minivan $9. You may also be approached y taxi drivers outside the border post, perhaps $40 for a taxi all the way to Siem Reap.
Onwards from Siem Reap to Phnom Penh: Spend a day or two in Siem Reap visiting the Angkor Wat temples. When you're ready to move on to PP, there are two options, bus or boat. There's a daily boat along the river from Siem Reap to Phnom Penh departing 06:30 and arriving 13:00. Distance 251km, fare $35. Alternatively, there are buses at various times throughout the day from 06:30 until about 12:30. Journey time 6 hours, fare around $10, distance 314km. Buses are run by several operators. Some buses are double-deck, some have a WC & refreshments.
