Visitors have the choice of a one-day pass (US$37), a three-day pass (US$62) or a one-week pass (US$72). The three-day passes can be used over three non-consecutive days in a one-week period while one-week passes can be used on seven days over a month.
In 2016, the Angkor ticket booth & main entrance moved to a new location out by the Siem Reap Convention Centre, about 2km east of the old checkpoint. It's part of a gleaming new complex that also includes the ambitious Angkor Panorama Museum. Tickets are not sold at the old ticket checkpoint.
Passes include a digital photo snapped at the entrance booth, so queues can be slow at peak times. Visitors entering after 5pm get a free sunset, as the ticket starts from the following day. The fee includes access to all the monuments in the Siem Reap area but not the sacred mountain of Phnom Kulen (US$20) or the remote complexes of Beng Mealea (US$5) and Koh Ker (US$10).
All the major temples now have uniformed staff to check the tickets, which has reduced the opportunity for scams. These days all roads into the central temples (including Angkor Wat, Angkor Thom and Ta Prohm) have checkpoints as well; foreigners who can't produce a pass will be turned away and asked to detour around the temples between 7am and 5pm. Visitors found inside any of the main temples without a ticket will be fined a whopping US$100.
