What to know before visiting Cambodia

Cambodia is a Southeast Asian nation whose landscape spans low-lying plains, the Mekong Delta, mountains and Gulf of Thailand coastline. Phnom Penh, its capital, is home to the art deco Central Market, glittering Royal Palace and the National Museum's historical and archaeological exhibits. In the country's northwest are the ruins of Angkor Wat, a massive stone temple complex built during the Khmer Empire.
