Mekong Express to Kampong Cham and then another bus to Kratie. It may take the entire day to do it. Mekong Express is airconditioned and comfortable.
I enjoyed very much my visit to Kratie with its hotels facing the Mekong and of course the most visited Tourist Attraction!
We had Mr.Roza as our driver the entire 3-day stay in Siem Reap. He's an energetic, diligent and courteous young man. He posses both taxi ($50/day) and tuktuk ($15/day), and services both long-haul (e.g. Poi Pet - Siem Reap) and short-haul within the city. Guarantee NO hassle or touting from this guy!
The Angkor temples are very spread out, and not easily reachable on foot. Therefore, it helps to have a motor vehicle to get around. You will also need a driver, a not all road signs are in Roman letters. Your options are a tuk-tuk (rickshaw pulled by a motorcycle) or a car. For a few dollars more, we recommend hiring a car with a driver, which will cover ground more quickly than a tuk-tuk and have air conditioning. We hired a man named Pop, who was excellent. He happened to be our cab driver from the airport to our hotel. His van was air-conditioned, and he drove us wherever we wanted for $25/day, which included drinks and gasoline. He drove us for five days, and was very user friendly. For a few dollars extra, he also took us to Beng Malea, a temple about 2 hours away, which was one of the highlights of our trip.
Tuk-tuks are covered offering some protection from sun and rain. In Siem Reap most drivers speak some English.
To the temples, transportation is usually rented by the day. Rates run about $10-$15/day for motorcycle trailers.
Bicycling is quickly becoming a popular way to visit the temples. The roads between the main temples are paved and the distances are about right for a bicycle touring. Bring sun screen, a good hat, water and a Cambodian scarf to keep the sun off your neck. Many of the guesthouses, hotels have bicycles for rent. $1.5-$4/day depending on the type and quality of the bike.
I found the best way to visit Angkor Wat was to rent a bicycle and ride out to the ruins before 7am. Yes, it is hot, yes, it is hard work, but with your guidebook in hand and good planning the night before i think it is far better than tuk-tuks, elephants etc. The info in your guidebook will tell you the history as well as the signs scattered around the area. If you are really interested in learning more, then by all means take a guide. I spent the whole day cycling around and saw all the major spots in the central area, and it was enough for me. Take plenty of water although drinks and snacks are available everywhere.
Now that the road is finally surfaced bus travel to Poipet is easy by bus, taking less than 3 hours. At Poipet you will probably have to take a smaller bus to the border then walk across. Then you can get a tuk-tuk to either the bus station or train station.
Warning!!! Do not take a night bus operating by Virak-Buntham Express Travel & Tour.
We bough a ticket apparently from VIP company, yet received Virak express tickets.
The bus was absolutelly crowded, not clean, and certainly not the one we have seen on the promotion poster. There was a sort of "Á/C", basically a box making an awful noise if nothing else, which was not possible to regulate or switch off, blowing a whole journey (11hrs) onto my face.
No toilet on the boadr, no food as advertised, the only thing we got was a 0.3l of water.
The driver made 2 stops during the journey, both by the main road so there was no chance to get a bit of a privacy unless you stepped into a dark spot where you could not seen where you are at all.
The staff does not speak english & we had difficulties to find our luggage at the end of this horrible journey.
According to the hotel owner who we have shared the story later with, the night buses are more less the same, whilst the day connections shall be of a better standard.
Our journey started from our hotel in Siem Reap,from here we traveled by mini bus for about 30 minutes before reaching the river.Here we boarded our small boat which took us up the river for a trip which lasted about 3 hours.On the way we passed several fishermen waist deep in water using a weighted fishing net,many floating homes where families survive by fish and crocodile farming.Many of the people live on the riverbank in very basic homes made of wooden poles covered with plastic sheeting.
Tuk-Tuk is the most convenient, economy choice of transportation. With $10 you can charter one for a day going around Angkor archeology park, or Tonle Sap (lake). $15 if you want to go a bit further, e.g., more than 15km distance. You only pay at the end of the day.
I recommend a local driver, his name is "Oad" (by pronunciation) kind and honest guy, drives very safe. His mobile is +855 92 742 921
Its best to rent a driver and a car for the entire day for US$ 20, its the best deal as some of the drivers also double as decent tour guides. However if you need a tour guide then get one too.
Unless you are a back packer and want to do it yourself, you are better off with this option as 20$ is bloody cheap for the whole day.
Siem Reap International Airport is very beautiful airport with modern architecture is based on the traditional Khmer style and its the second largest airport in Cambodia.
