At 475,440 km2 (183,570 sq mi), Cameroon is the world's 53rd largest country. It is slightly larger than the nation of Sweden and the US state of California. It is comparable in size to Papua New Guinea. Cameroon's landmass is 472,710 km2 (182,510 sq mi), with 2,730 km2 (1,050 sq mi) of water.
Cameroon is sometimes described as "Africa in miniature" because it exhibits all the major climates and vegetation of the continent: mountains, desert, rain forest, savanna grassland, and ocean coastland. Cameroon can be divided into five geographic zones. These are distinguished by dominant physical, climatic, and vegetative features.

Cameroon's coastal plain extends 20 to 80 kilometres (10 to 50 mi) inland from the Gulf of Guinea (part of the Atlantic Ocean) to the edge of a plateau. In the former western state, however, the mass of Mount Cameroon reaches almost to the sea. The plain is densely forested including areas of Central African mangroves especially around Douala and in the estuary of the Cross River on the border with Nigeria.
A recent global remote sensing analysis suggested that there were 643 km2 of tidal flats in Cameroon, making it the 39th ranked country in terms of tidal flat area.[1]
The low South Cameroon Plateau, rising from the coastal plain and dominated by tropical rain forest, has an average elevation of 500 to 600 metres (1,500 to 2,000 ft). It is less humid than the coast.
In western Cameroon is an irregular chain of mountains, hills, and plateaus that extends from Mount Cameroon almost to Lake Chad at the northern tip of the country. This region includes the Bamenda, Bamiléké, and Mambilla highlands. It also contains some of the country's most fertile soils, notably around volcanic Mt. Cameroon. This area of tropical forest has been categorised by the World Wildlife Fund as the Cameroonian Highlands forestsecoregion with Mount Cameroon considered separately because as an active volcano it has a distinct environment from the other mountains.
From the forested southern plateau the land rises northward to the grassy, rugged Adamaoua (Adamawa) highlands. Stretching across Cameroon from the western mountain area, the Adamaoua forms a barrier between the north and south. Its average elevation is 1,000 m (3,400 ft).
The southern savanna plain extends from the edge of the Adamaoua to Lake Chad. Its characteristic vegetation is scrub and grass. This is region of sparse rainfall and high median temperatures has been included as part of the East Sudanian savanna ecoregion.
Climate
The climate varies with terrain, from tropical along the coast to semiarid and hot in the north.
Exceedingly hot and humid, the coastal belt includes some of the wettest places on earth. For example, Debundscha, at the base of Mt. Cameroon, has an average annual rainfall of 10,300 millimetres (405 in).[2]
The wide diversity of climates and natural regions of Cameroon, as coastline, mountains, savanna, deserts, and tropical forests, allows that the country counts with rich biodiversity. Twenty-two million hectares from the Congo Basin forest ecosystem are located in Cameroon, where 9,000 plant species, 900 bird species, and 320 mammals species live,[11] included 156 endemic plants, eight endemic birds, and 14 endemic mammals. The border with Nigeria has one of the highest concentration of biodiversity in Africa.[12]
As part of the conservation efforts to protect threatened natural resources, Cameroon has established protected areas since 1932, included national parks, wildlife sanctuaries, faunal reserves, and one flora sanctuary.[13]

The country has four patterns of drainage. In the south, the principal rivers flow southwestward or westward directly to the Gulf of Guinea – the Wouri, and lesser Dibamba, Bimbia and Mungo to the Cameroon estuary near Douala; Sanaga, Nyong, and Ntem further south along the coast; Akwayafe and Manyu (which joins Nigerian Cross), and the lesser Ndian and Meme north of the coast.[15] The Dja and Kadeï, however, drain southeastward into the Congo River. In northern Cameroon, the Benoué River (Benue) runs north and west, eventually into the Niger, while the Logone River flows northward into Lake Chad.
Some of the borders of Cameron follow rivers, including the Aïna, Akwayafe, and Ntem or Campo.
Geography – note:
sometimes referred to as 'the hinge of Africa;' throughout the country there are areas of thermal springs and indications of current or prior volcanic activity; Mount Cameroon, the highest mountain in Sub-Saharan west Africa, is an active volcano
