Perched within the heart of Mainland Southeast Asia and bordered by the Gulf of Thailand, Cambodia is a kingdom defined by its vast alluvial plains and the mighty pulse of the Mekong River. The northern jungles conceal the architectural titan of Angkor Wat, a celestial stone tapestry that serves as the world's largest religious monument. This is also an ideal destination for culture enthusiasts worldwide. Beyond the iconic spires of Siem Reap, the capital of Phnom Penh stands at the "Four Faces" confluence of rivers, blending the golden-roofed Royal Palace with the somber, reflective history of the Tuol Sleng Genocide Museum.
