A UNESCO World Heritage site, Angkor Wat is one of the most mysterious temples in the city of Siem Reap, Cambodia. The hidden "village" (it's more like a never-ending maze of wats and cultural confusion) was re-discovered by the French in the 19th century and literally cut out of the jungle. Upon arrival in Siem Reap, you have your pick of motorbike, taxi, or tuk-tuk tour guides to take you through the life of the city, from 3-day tours to 24-hour wat-a-thons.
One of the most intriguing aspects of the temples is the mix of Buddhist and Hindu power that was obviously traded over years of rulers. This is a can't-miss for history buffs and anyone out there who likes a good mystery. Between the people, the temples, the nightlife, and the extremely reasonable prices, Siem Reap is a great time.
