Located along the Gulf of Guinea and bordered by Benin, Niger, Cameroon and Chad, Nigeria is Africa’s most populated country. Nigeria’s southern coastal areas have large swathes of mangrove forests and swamps but the inland is thickly forested and boasts of a diverse wildlife. River Niger flows through western Nigeria and is deposited into Gulf of Guinea. Nigeria has a very diverse landscape with coastal plains in both southeast and southwest. In the southeast is located the Obudu Plateau as well as the Mambilla plateau, the highest plateau in Nigeria which runs deep into neighboring Cameroon. The southwest is however, a rugged mountainous area. The major topographical feature of Nigeria consists of the Niger and Benue river valleys. Both these valleys join each other to form a ‘Y’ shape. Nigerian waters are affected by pollution and the visibility underwater is reported to be poor, which is not a good news for divers thinking of heading to the country. However, the security situation in the country has nose dived in recent years and It is advisable that the potential tourists may check the internal situation of the country before planning a visit.
