The greatest jewel of Cambodia is Angkor Wat and all the ancient temple complexes surrounding it. I won't get into much detail about what Angkor Wat is because you can Wiki it for yourself and gain some knowledge along the way. Words cannot describe how awe-inspiring these ancient ruins can be. In person, they are mammoth and makes you wonder how the heck did the people from back then manage to do this. The ruins are almost 1000 years old and still standing. Time and war have done some damage over time but it still is magnificent to behold. We spent 3 days wandering through about 12 of the main temple complexes but there are lots more that we didn't get a chance to see because of time constraints and because our feet were killing us.
