When to go to Siem Reap?

Siem Reap exists for Angkor, and most days start in the dark to reach the temple ponds before sunrise. The towers of Angkor Wat come first, then the stone faces of the Bayon inside Angkor Thom, then Ta Prohm, where fig roots pour over the galleries. Phnom Bakheng takes the last of the light, and the night markets deal in amok curry, palm sugar and tired legs.
