The name Siem Reap literally means "Siam Defeated". These days, however, the only rampaging hordes are the tourists heading to the Angkor Archaeological Park. This once quaint village has become the largest boomtown and construction site in Cambodia. It is quite laid-back and a pleasant place to stay while touring the temples. It is a nice compromise between observing Cambodian life and enjoying the amenities of modern services and entertainment, thanks to a large expatriate community. Since Siem Reap is a major tourist destination, prices in some instances are higher than elsewhere in Cambodia. Expect to receive almost constant offers for motodop and tuk-tuk rides, along with everything else which drivers may be able to offer to you.
