Passes are required to enter the Angkor area. They are on sale at the front gate for 1 (US$20), 3 (US$40), or 7 (US$60) days, which must be used consecutively. (Cambodians can enter for free - you shouldn't need to buy a pass for your guide or your driver.) If you buy a pass on the evening before the first day of the pass, you can enter the park after 5PM to view the sunset, after which the park closes. A passport photo is required for the 3 and 7 day passes, which are non-transferable.
