Cambodian can be divided in the following four geographical regions:
The Cardamom and Elephant Mountains, coast and archipelago
The Cardamom and Elephant Mountains is a range that starts in the east of Thailand and cross Cambodia from southwest to southeast separating the Central Plains from the Cambodian coast.
The north of the Cardamom and Elephant Mountains include the provinces of Pailin, Battambang and Pursat.
The south of the range includes the coastal provinces of Cambodia: Koh Kong, Kompong Saom, Kampot and Kep.
In this region it is located the highest Cambodian pick, the Aroul Mountain (1,813 meters up the sea level.)
The Cambodian Northwest includes the Dangrek Mountains that divide northern Cambodia from the Thai region of Isaan. This is also the region of the Angkor Archaeological Park in Siem Reap, the busy casinos of Poipet at the Thai border, the Sap Lake, Preah Vihear, Oddar Meanchey – last stronghold of the Khmer Rouge guerrilla and the Sambor Prei Kuk pre-Angkorian temples of Kompung Thom.
