The Central African Republic is bordered to the north by Chad, to the east by Sudan, to the south by the Democratic Republic of Congo and the Republic of Congo, and to the west by Cameroon. It is a large, landlocked territory of mostly uninhabited forest, bush and game reserves. The Chari River cuts through the centre from east to north; towards the Cameroon border the landscape rises to 2,000m (6,560ft) west of Bocaranga in the northwest corner, while the southwest has dense tropical rainforest.

The northeast becomes desert scrubland and mountainous in parts
