From atop Phnom Bakheng, you can see the ancient Angkor Wat temple in the distance. It might not look as far in this photo, but that's because I zoomed in quite a bit (9x) to get this view. I think it's pretty cool looking down on the massive temple, with its lotus bud towers piercing above the trees. Amazing when all that surrounds it is the jungle and additional temples.
