Once on the bus you will pass by the airport and Chom Chao Flyover which is a multilevel junction where national road 3 and 4 start. Once there tell the conductor that you want to get off at [https://goo.gl/maps/AtBaATTyDouaUjAP6 Total] gas station which is on the right hand side. Just before Total there is a PTT gas station on the left. The bus ride is 1500 riel, cash only, no change given. The national road 3 was upgraded to dual carriageway standard in 2022, but it's not a motorway so pedestrians, bicycles and motorbikes are allowed.

Otherwise, head south on Chamkar Doung Road (Road 271) towards the Killing Fields (ជើងឯក) from the Sokimex Petrol Station, and hitchhike from there.

You can hitch just after [https://goo.gl/maps/Kwrmt33Mcm9Nxzhs8 Phrom Bayon Statue and roundabout] on the eastern side of Chroy Changvar Bridge, where National Road 6 starts. You can get here from Monivong Boulevard by bus 1 heading north (1500 riel, cash only, no change given). Make sure to make a sign as first of all you will have a lot of local traffic here, and secondly the roads later split. The NR6 continues northwest towards Siem Reap, but if you want to go to Kratie (Kracheh) and towards Laos you have to take NR7 which starts 70 km north from this spot.

From Monivong Boulevard take the public bus line 1 as far north as it goes which should be somewhere around [https://goo.gl/maps/3oVvGYxYRWLNsrdn9 Prek Pnov Market] and walk further north to find a good spot. There is a Sokimex petrol station with a lot of space for cars to stop. Alternatively take a tuk tuk just north of Chroy Changvar bridge [approx. 11.5872N, 104.91914E], which usually go as far as Udong (about 40km away).
