If you are an ASEAN citizen, a visit to the nearby Angkor Archaeological complex in Cambodia ought be on your bucket list. Not just any visit though. Go to the temple at 6 am. Sit cross-legged under a shady Bodhi tree in front of the moat. Put your camera down. Treat your eyes to the most magical breaking of dawn as how the Hindu kings saw it in the early 12th century. Then take a picture.
To get there so early in the morning, you should make arrangement for transport the day before and obtain your multiple-entry pass before hand. A tripod is not necessary but handy. There will be a lot of climbing and walking to do, so carry a lightweight one if you must. See also the sunset pic from a nearby area, in my gallery.
