Visit the Angkor temples

The temples are what everyone's here for, and Angkor doesn't disappoint. Whether you're a hardcore shutterbug or just want to see the temples at their best, a photography tour will make sure you don't miss the hidden highlights.
The best time for photos is sunrise -- go in April to see the sun crest the horizon immediately behind the main shrine's dome and to maximize your chances of a haze-free day.
Or, if you don't mind sweating, rent a White Bicycle at any of the stands in town (your $2 daily rental fee helps support local NGOs) and spend the day seeing the main temple circuit -- Angkor Wat, Angkor Thom and Ta Prohm -- at your own pace.
Either option gives you plenty of time to see the big three, any smaller temples that catch your eye, and still make it to Phnom Bakeng for the best sunset views.
