Kenya is a sovereign state in the African Great Lakes region of East Africa. Its capital and largest city is Nairobi. Kenya lies on the equator with the Indian Ocean to the south-east, Tanzania to the south, Uganda to the west, South Sudan to the north-west, Ethiopia to the north and Somalia to the north-east. Kenya covers 581,309 km2 (224,445 sq mi). It has a warm and humid climate along its Indian Ocean coastline, with wildlife-rich savannah grasslands inland towards the capital. Nairobi has a cool climate that gets colder approaching Mount Kenya, which has three permanently snow-capped peaks. Further inland, there is a warm and humid climate around Lake Victoria, and temperate forested and hilly areas in the western region. The northeastern regions along the border with Somalia and Ethiopia are arid and semi-arid areas with near-desert landscapes. Lake Victoria, the world's second largest fresh-water lake and the world's largest tropical lake, is situated to the southwest and is shared with Uganda and Tanzania. Kenya is famous for its safaris and diverse wildlife reserves and national parks such as the East and West Tsavo National Park, the Maasai Mara, Lake Nakuru National Park, and Aberdares National Park.
