Getting around Siem Reap is incredibly easy, a lot easier than getting around Phnom Penh that's for sure. Taxi's or motos (a motor bike with a trailer on the back) is a fun way to travel around Siem Reap and unlike Phnom Penh, a lot of the cabbies know English.

Taxis are usually a/c Toyota Camrys; they  take 4 persons for $25  for full day at temples. There is an extra charge for tours outside of the Angkor Park and a few $ extra for sunrise (April 2007)

Motos (small motor bikes) are everywhere and hailing one down is as easy as walking out the front of your hotel, standing on the side of the road or by just looking over at them!! Generally moto taxis costs $1 per person around town. You can get it down to $3 for 4 people; and about $8-10 for a full day at the Temples (August 2008)

The moto taxi with the trailer on the back can  fun way to travel around the city and the temple area.  The trailer has  bench seats and a roof over  the top. You can have a good look around and talk to your companions while you travel from A to B. 

The price to travel on these moto trailers is usually $12 for the Angkor temples  for full day.  Moto trailers can hold up to 4 people but 2 is safer as they are unstable  with poor brakes .  They can be dangerous in the wet. So a car is far preferable in the rain. 

Don't forget the most important thing about travelling around anywhere in Cambodia and Siem Reap . Make sure that you agree to a price before you travel with a moto rider or taxi driver!! Cambodians do all their business by haggling and taxis are definitely included into haggling.  Don't go overboard with the haggling trying to get the lower price, since these taxi drivers and moped riders rely on the job, and your fare, to feed their families.

A good and reliable taxi company ,which is a joint Irish and Cambodian business is  www.siemreaptaxis.com.

 Another one to consider is Mr. John.

And highly recommended Sam a private Angkor Wat Driver,courteous , punctual and English spoken  http://.www.angkordriver-sam.com  and you might have a look at http://www.angkor-guides.com/

Temple passes are $20 per day $40 3 days and $60 for 7 days payable at the main ticket offices on the way into the park. (you cannot buy passes anywhere else). Unlike before, you now need not bring along a photo. The cams at the ticket counters (like at Siem Reap airport) will take care of that.

Please note: Taxi  or moto Drivers are not allowed to guide tourists in the Angkor Park . if you need a guide; these must be booked in advance as none are available within the Temples. The cost of a fully licenced guide is $25 per day excluding driver and vehicle. Your hotel should be abble to arrage for you.  A car and driver (including petrol) costs about $30 per day and a 14 seater van and driver costs about $35 per day around the Angkor area. For trips to Kbal Spean, Banteay Srei and beyond, there is usually a surcharge.
