Discover Cambodia. Includes FREE planning and background information. Back in the 1960s, Siem Reap (see-em ree-ep) was the place to be in Southeast Asia and saw a steady stream of the rich and famous. After three decades of slumber, it-s well and truly back and one of the most popular destinations on the planet right now. The life-support system for the temples of Angkor, Cambodia-s eighth wonder of the world, Siem Reap was always destined for great things, but few people saw them coming this thick and this fast. It has reinvented itself as the epicentre of the new Cambodia, with more guesthouses and hotels than temples, world-class wining and dining and sumptuous spas.
