1. Siem Reap
There is no other place to start than the most famous destination in Cambodia: Siem Reap. The popularity of Siem Reap is twofold: it is the closest city to Angkor Wat (first time), and it’s a backpacker party paradise. Siem Reap is easily reached by air or by bus from Laos and Thailand. It is also one of the most affordable destinations in Southeast Asia, with low prices for food, drinks and accommodation.
2. Phnom Penh
Although Siem Reap may be the top tourist destination, Phnom Penh is the capital of Cambodia. It is a modern city accessible by air or by bus from Vietnam. The city is big and relatively modern, with bustling markets and lovely temples. But both of the main tourist attractions in Phnom Penh are memorials to the Cambodian Genocide.
