Angkor Wat is the largest and most spectacular monument of Angkor, not write more because you'll have all your guides to detailed directions, but I will talk about the cache.
In the visit, I was surprised that in these very popular temple there is already a cache was located. So as I moved inside, in a moment of pause sitting on a stone, my eye fell in a place where a cache was just fine there and I placed there.
The place is popular with Muggles, but identified GZ even with the spoiler, you stand comfortably sit, relax and at the right time in that moment that no one sees you operate the log. (Small note on cache maintenance: There is a local guardian)
Good hunting !!!
