Kenya has a warm and humid tropical climate on its Indian Ocean coastline which becomes cooler as you move inland through the wildlife-rich savannah grasslands towards the capital. The capital city, Nairobi, has a predominantly cool climate which becomes colder as you move closer to Mount Kenya, which has snow permanently on its peaks. Further inland, in the Nyanza region, there is a hot and dry climate which becomes humid around Lake Victoria, the largest tropical fresh-water lake in the world. This gives way to temperate and forested hilly areas in the neighbouring Western region. The North-Eastern regions along the border with Somalia and Ethiopia are arid and semi-arid areas with near-desert landscapes. Kenya is traditionally famous for its safaris, diverse climate and geography, and expansive 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. Kenya has several world heritage sites such as Lamu and numerous world-famous beaches including in Diani, Bamburi and Kilifi where international yachting competitions are held every year.
