Angkor Wat
historicalThe world's largest religious monument and Cambodia's crown jewel, built in the 12th century by King Suryavarman II. This UNESCO World Heritage Site sprawls across 400+ acres with intricate bas-reliefs depicting Hindu mythology and Khmer history. Originally a Hindu temple dedicated to Vishnu, later converted to Buddhism. Sunrise here is legendary but extremely crowded - consider sunset for fewer tourists. A 1-day pass costs $37, 3-day pass $62, 7-day pass $72. Absolutely unmissable.
