The Central African Republic is a landlocked country, bordered by Chad, Sudan, South Sudan, Democratic Republic of the Congo, Republic of the Congo, and Cameroon. Much of the country consists of flat or rolling plateau savanna approximately 500m above sea level. In addition to the Fertit Hills in the northeast, there are scattered hills in the southwest regions. In the northwest is the Yade Massif, a granite plateau with an altitude of 348m. The country also includes a Sahelo-Sudanian zone in the north and an equatorial forest zone in the south. Two thirds of the country is within the Ubangi River basin (which flows into the Congo), while the remaining third lies in the basin of the Chari, which flows into Lake Chad.
