There are direct flights to the capital of Phnom Penh from Bangkok, Hochiminh, Kualalumpur, Singapore, Hongkong, Vientiane and Guangzou. All of these cities serve as gateways to Cambodia meaning Cambodia is easily reached from further a field. Cambodia can also be reached by road from Thailand and Vietnam. Another exotic way to reach Cambodia is by river boat or sea cruise.
Direct flights exist from Bangkok to Siem Reap, the home of Angkor Wat.
