November to February is the best time of year to travel, but this is no secret, so it coincides with peak season. And peak season really is mountainous in this day and age, with more than two million visitors a year descending on Angkor.

The Angkor Wat International Half Marathon takes place annually in December, including the option of bicycle rides for those not into running.
