Most people don't realize that the Angkor Archaeological Park is more than just the famous Angkor Wat temple. With over 1,000 temples in all, this vast area calls for more than one day to explore. A one-day ticket is $37, while a three-day pass is $62 and packs more value in that you have more time to come see the entirety of the grounds. You can even opt for a seven-day ticket for $72 if you're staying for a while and would prefer to spread out your time. But if you only have one day, opt for the two most popular ruins: Angkor Wat and nearby Angkor Thom.
