Watching sunrise and sunset in Angkor Wat is an iconic travel experience. Even though crowds of people come to see it, you should be there as well. The view is stunning. Temple shapes slowly become visible in soft blue and purple sunlight at the morning and illuminate in red and orange light at the evening.
The best time in a year to see this beauty is from April to October when lotus pound around the temple is full of blooming flowers. So the light and temple silhouette are reflecting on the water among them.
