Linger in the echoing corridors of the sprawling monastic city of Preah Khan, walk the scenic wooden boardwalk over flooded forests to the island sanctuary of Neak Pean, and photograph the famous tree-strangled eastern gate of Ta Som. After admiring the giant stone elephants at East Mebon, morning tours beat the midday heat, while afternoon tours wrap up atop the ancient bricks of Pre Rup, watching the sun sink over the endless jungle canopy.
