Bayon is one of my favorite temples in the Angkor Archaeological Park. The more than 200 stone faces provides a number of different photographic opportunities - pose nose to nose with a stone face or with your facial silhouette within the stone's silhouette or just one stone face in front of another. My favorite times to visit are early morning and especially late in the day when the number of visitors dwindles. You can actually find some quiet time amongst the many faces before the sun sets. Bayon was built in the late 12th century, as a Buddhist temple, under the reign of Jayavarman VII. Bayon is not a large area. There are a number of photo ops where visitors like to pose in front of the stone faces or peek out of one of the many windows. Visiting early (arriving by 6:45 am) or later in the day (an hour and a half before sunset) allows for easier access to these shots.
