The pools make Angkor Wat even more interesting to photograph, because of the addition of natural symmetry.
Angkor Wat - Opening Hours are from 5am to 6pm.
Cambodia is located near to the Equator, thus the opening hours (5am) allow you to get to the temple before sunrise and leave after sunset (6pm).
The shots was taken outside the Angkor Wat at around 6.15pm.
