Equatorial Guinea consists of two parts, an island and a mainland region. The island region consists of the islands of Bioko in the Gulf of Guinea, and Annobón, a small volcanic island south of the equator. The capital Malabo is on Bioko Island. The mainland region is Río Muni, where Bata, the largest city, and Oyala, the country's planned future capital, are located. Rio Muni also includes several small offshore islands, such as Corisco, Elobey Grande, and Elobey Chico.

Geographical Setting

Equatorial Guinea consists of two parts, an island and a mainland region. The island region consists of the islands of Bioko in the Gulf of Guinea, and Annobón, a small volcanic island south of the equator. The capital Malabo is on Bioko Island. The mainland region is Río Muni, where Bata, the largest city, and Oyala, the country's planned future capital, are located. Rio Muni also includes several small offshore islands, such as Corisco, Elobey Grande, and Elobey Chico.
