Natural Landmarks in Cambodia
Cambodia, located in Southeast Asia, shares borders with Thailand to the west, Laos to the north, Vietnam to the east, and the Gulf of Thailand to the south. The country covers approximately 181,000 square kilometers, and its terrain is dominated by low-lying central plains, which are surrounded by mountain ranges and plateaus. The Mekong River, one of Southeast Asia’s most important waterways, runs through the heart of Cambodia, nourishing the fertile lands that make agriculture a significant part of the country’s economy. Cambodia’s landscape is also shaped by the vast Tonle Sap Lake, a UNESCO Biosphere Reserve that fluctuates dramatically in size between wet and dry seasons. Despite its tropical climate and historical sites like Angkor Wat, Cambodia’s natural landscapes—ranging from dense rainforests and rolling hills to coastal islands and waterfalls—are less known but offer breathtaking beauty and biodiversity.
