Siem Reap is the gateway to the temples of Angkor, which are clustered together within Angkor Archaeological Park, the entrance of which lies about five miles north of the city. Though it seems like a chaotic sprawl of hotels and markets, Siem Reap actually follows an orderly grid of city blocks. The … more tourist action lies west of the Siem Reap river, but a walk across any bridge brings you right back to the authentic Cambodian flavor of the east side neighborhood of Wat Bo.
