Kenya has a warm and humid tropical climate on its Indian Ocean coastline. The climate is cooler in the savannah grasslands around the capital city, Nairobi, and especially 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 neighboring 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 known 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 beaches, including in Diani, Bamburi and Kilifi, where international yachting competitions are held every year.
