About Cambodia

The Mekong River and Tonle Sap lake form the heart of Cambodia, with the Gulf of Thailand in the south. The Angkor temple complex near Siem Reap is the best-known site, with Phnom Penh's royal palace and the southern beaches around Sihanoukville and Kep. The dry, cooler months from November to March are the most comfortable, the hot season from March to May is harsh, and the monsoon from May to October brings heavy rain and green hills.
