Poipet - Aranyaprathet land border Thailand - Cambodia
Poipet hosts Cambodia's main border crossing with Thailand, which links north-western Cambodia to Aranyaprathet, and hence Bangkok. Cross-border activity has made the town grow to be larger than its provincial capital, Sisophon.
It is located on the fully paved National Highway 5 which runs to Sisophon and then further on the south side of the Tonle Sap Lake to Battambang and Phnom Penh. At Sisophon, National Highway 6 branches off to provide a fully paved arterial route along the north of the Tonle Sap to Siem Reap and Phnom Penh.
