Mynah on Naga
It is possible to take photos of Angkor Wat without people even when it's late in the morning. Enter from the back, instead of the front - the throng of people coming in through the front would be inside the structures and for some reason, only a few people would be wandering the grounds.
Naga is the 7-headed serpent prevalent in Hindu mythology. Angkor Wat was constructed as a Hindu temple dedicated to the god Vishnu .
