Angkor Thom South Gate is most popular with visitors, as it has been fully restored and many of the heads (mostly copies) remain in place. The gate is on the main road into Angkor Thom from Angkor Wat, and it gets very busy at peak times. It is very good time in the morning to visit it so you can avoid the crowd  and sometime you  can watch sunset from this gate because you can see sunshine on statues of God and demon.
