Why should you go there and how do you do it right?

Khmer architecture in Thailand is rarely more perfect than here. The temple sits atop an extinct volcano and was built between the 10th and 13th centuries as a stone model of Mount Meru, the sacred mountain of Hindu cosmology. The complex fulfills its purpose perfectly. One ascends the ceremonial staircase, passes through the gopuram gates, and finally reaches the main prang. From there, one has a sweeping view of the flat landscape stretching out in all directions. The pink sandstone and laterite are the main attraction, as are the remarkably well-preserved door lintels decorated with mythological scenes.

Four times a year, at sunrise, the sun is directly overhead, shining a single ray through all fifteen doors. This attracts many visitors. On all other mornings, you'll have the place almost entirely to yourself, which, in my opinion, is a better trade-off. Nevertheless, arrive early, as the staircase is unshaded and the stone retains the heat.
