Angkor Visitor Passes and Fees
An official pass is required for admission to any temple or monument in the main Angkor complex and most other temples and monuments in the Siem Reap area. Angkor passes can be purchased at the sales booths on the main road from Siem Reap to Angkor Wat (~4 km north of the Old Market), at the checkpoint on the road from the airport to Angkor Wat, and at the checkpoint at Banteay Srei. No one else is authorized to sell Angkor passes and they are not transferable. You no longer have to bring a passport picture. They will take your picture there. You will be required to show your pass at each temple and monument.
When I visited in Mar 09, there were three options for passes: one day (US$20), three consecutive days (US$40) and seven consecutive days (US$60); however, the new ticketing rules which started on 1 Jul 09 allow the US$40 passes to be valid for any three days during a week instead of three consecutive days, and the US$60 tickets are usable for any seven days during a month. Make sure you get one of the new passes! The fee must be paid in US dollars, Cambodian Riel, Thai Baht or Euro. Credit cards are not accepted for payment, but there is a bank counter at the sales booths, where visitors can get a cash advance on their credit card. There are separate windows at the sales booths for each length of pass. Be sure to check on both sides of the building.
It is not cheap to visit the Angkor temple complex. Besides the pass, if you want a guide to accompany you into the temples, they must be licensed and the cost is typically $20-25 per day. A tuk tuk costs $12-15 per day. A tuk tuk driver can only take you to a temple and cannot be a guide. BTW, the Angkor pass includes free use of the restrooms that are now outside many of the main temples in the complex. Evidently there used be very few restrooms but when a VIP visitor had a hard time finding one, that was changed.
