About Siem Reap

The town of Siem Reap (សៀមរាប), in northern Cambodia, is the primary access point for the Angkor Archaeological Park, just north of the city. 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 foreign community.
