Angkor, the ancient capital of the Khmer kingdom is one of the wonders of the world. A huge area full of temples and relics of antiquity. The highlight of the region is Angkor Wat, the great temple is simply unsurpassed by any other monument, and is said to be one of the places to see before you die. I don't disagree! Another worthwhile destination near the city of Siem Reap is Tonlé Sap, Cambodia's great lake.
