The Kingdom of Cambodia (????????????????????? ? ?????????????) (sometimes transliterated as Kampuchea to more closely represent the Khmer pronunciation) is a Southeast Asian nation bordered by Vietnam to the east, Laos to the north, Thailand to the northwest, and the Gulf of Thailand to the southwest. Contemporary Cambodia is the successor state to the mighty Khmer empire, which, during the Angkorian period, ruled much of what is now Laos, Thailand and Vietnam. The remains of this empire can be seen at the fabled temples of Angkor, monuments unrivalled in scale and grandeur in Southeast Asia. The traveller’s first glimpse of Angkor Wat, the ultimate expression of Khmer genius, is sublime and is matched by only a few select spots on earth, such as Machu Picchu or Petra.

Ninety percent of Cambodia's population is of Khmer origin and speak the Khmer language, the country's official language. Cambodia's population is relatively homogeneous. Its minority groups include Vietnamese (5%) and Chinese (1%).

Just as Angkor is more than its wat, so too is Cambodia more than its temples, and its urban areas can surprise with their sophistication. Chaotic yet charismatic capital Phnom Penh is a revitalised city earning plaudits for its gorgeous riverside location, cultural renaissance, and world-class wining-and-dining scene. Second city Siem Reap, with cosmopolitan cafes and a diverse nightlife, is as much a destination as the nearby iconic Angkor temples. And up-and-coming Battambang, reminiscent of Siem Reap before the advent of mass tourism, charms with graceful French architecture and a thriving contemporary art scene.

Cambodia's climate, like that of the rest of Southeast Asia, is dominated by monsoons, which are known as tropical wet and dry because of the distinctly marked seasonal differences.
Cambodia has a temperature range from 21 to 35 °C (69.8 to 95.0 °F) and experiences tropical monsoons. Southwest monsoons blow inland bringing moisture-laden winds from the Gulf of Thailand and Indian Ocean from May to October. The northeast monsoon ushers in the dry season, which lasts from November to April. The country experiences the heaviest precipitation from September to October with the driest period occurring from January to February. Cambodia has two distinct seasons. The rainy season, which runs from May to October, can see temperatures drop to 22 °C (71.6 °F) and is generally accompanied with high humidity. The dry season lasts from November to April when temperatures can rise up to 40 °C (104 °F) around April. Disastrous flooding occurred in 2001 and again in 2002, with some degree of flooding almost every year.
