Which African country's highest elevation point is Mont Ngaoui at 1,420 meters?

Mont Ngaoui, the 1,420-meter high point named in the question, is in the Central African Republic. It lies near the country's western border with Cameroon and is recognized as the nation's highest elevation point.

Mont Ngaoui is part of a mountainous border region rather than an isolated peak deep inside the country. The mountain's summit is associated with the Ngaoui area, and the international boundary passes through the surrounding highlands. Its elevation is also sometimes listed as approximately 1,410 meters, reflecting differing surveys and reference sources.

The Central African Republic is a landlocked country in the center of Africa, bordered by Cameroon, Chad, Sudan, South Sudan, the Democratic Republic of the Congo, and the Republic of the Congo. Despite its name and generally elevated plateau landscape, it is not dominated by extremely high mountains. Mont Ngaoui's height is modest compared with Africa's famous peaks, but it still makes the mountain the country's geographic high point.
