Kenya operates one of the most commercially developed wildlife park systems in Africa. The country contains 23 national parks, 28 national reserves, 4 national marine parks, 6 national marine reserves, and 4 national sanctuaries under Kenya Wildlife Service management as of 2024. These protected areas cover approximately 44,359 square kilometers, or 7.6 percent of Kenya's total land area. The system generates approximately 70 percent of Kenya's tourism revenue, which contributed 10.0 percent to national GDP in 2022 according to Kenya National Bureau of Statistics figures. Park infrastructure varies from paved roads and lodges in flagship reserves to minimal facilities in remote northern parks.
Maasai Mara National Reserve occupies 1,510 square kilometers in southwestern Kenya along the Tanzania border. The reserve forms the northern section of the larger Serengeti-Mara ecosystem, which spans 25,000 square kilometers across both countries. Between July and October each year, approximately 1.3 million wildebeest and 200,000 zebras cross the Mara River from Tanzania's Serengeti into the Maasai Mara, creating what tourism operators call the Great Migration. The crossing concentrates at specific points including the Mara River's lookout hill crossing point. The reserve contains an estimated 95,000 Thomson's gazelles, 18,000 topis, 12,000 impalas, and Kenya's densest lion population at approximately 850 to 900 individuals according to 2019 Kenya Wildlife Service census data. Narok County Council administers the reserve rather than Kenya Wildlife Service, creating a separate management structure from national parks. Daily conservancy fees in 2024 range from 80 to 100 US dollars for non-resident adults depending on season.
Tsavo National Park divides into Tsavo East and Tsavo West, together forming Kenya's largest protected area at 21,812 square kilometers. Tsavo East covers 13,747 square kilometers and contains the Yatta Plateau, a 290-kilometer lava flow that forms one of the world's longest lava flows. The park's red elephants gain their color from dust-bathing in the area's iron-rich red soil rather than from genetic variation. Tsavo West spans 8,065 square kilometers and includes Mzima Springs, which produces 250 million liters of water daily from underground rivers originating in the Chyulu Hills. An underwater observation chamber built at Mzima Springs in 1968 allows direct viewing of hippos and fish in the spring pools. The Ngulia Rhino Sanctuary within Tsavo West contains approximately 100 black rhinos within an electrified 90-square-kilometer enclosure established in 1986. Both sections suffered severe poaching between 1973 and 1988 when elephant populations dropped from an estimated 35,000 to approximately 5,300 individuals.
Amboseli National Park covers 392 square kilometers in Kajiado County at the base of Mount Kilimanjaro across the Tanzania border. The park provides the most widely photographed views of Kilimanjaro's 5,895-meter summit from Kenyan territory, though the mountain itself lies entirely in Tanzania. Swamps fed by Kilimanjaro's melting glaciers through underground channels create permanent water sources supporting approximately 1,600 elephants according to 2021 Amboseli Trust for Elephants census figures. Researcher Cynthia Moss has studied individual elephants in Amboseli continuously since 1972, creating the world's longest-running wild elephant research project. The park's soil contains high concentrations of natron and other minerals that create dry lake beds including Lake Amboseli, which floods during heavy rains but remains dry most years. Observation Hill offers 360-degree views across the park from a former volcano core. Daily park fees for non-resident adults cost 60 US dollars in 2024.
Samburu National Reserve, Buffalo Springs National Reserve, and Shaba National Reserve form a connected protected area complex totaling 392 square kilometers along the Ewaso Ng'iro River in northern Kenya. The reserves support five species uncommon elsewhere in Kenya that wildlife guides call the Samburu Special Five: Grevy's zebra, reticulated giraffe, Beisa oryx, Somali ostrich, and gerenuk. Grevy's zebras number approximately 2,000 individuals across northern Kenya according to 2016 surveys, making them more endangered than black rhinos by total population. The Ewaso Ng'iro River flows year-round despite the surrounding semi-arid landscape receiving less than 350 millimeters of annual rainfall. Elephants in Samburu wear GPS collars as part of the Save the Elephants research organization's monitoring program begun in 1998. The reserves contain approximately 900 elephants that migrate seasonally across unfenced boundaries. Joy Adamson released Elsa the lioness in the nearby area documented in "Born Free," though the actual release site at Meru National Park lies 150 kilometers southeast.
Nairobi National Park occupies 117 square kilometers immediately south of Nairobi's city center, creating the only protected area bordering a capital city globally. Skyscrapers in Nairobi's Upper Hill district appear in wildlife photographs taken from the park's Ivory Burning Site monument. The park supports approximately 50 black rhinos, four lions, 50 buffalo, and numerous plains game despite its small size and proximity to a city of 4.4 million people. The park's southern boundary remains unfenced to allow wildlife migration to the Athi-Kapiti ecosystem, while electric fencing on other sides prevents animals from entering residential areas. Established in 1946, it became Kenya's first national park. The park contains the Nairobi Animal Orphanage, which houses injured and orphaned animals unable to return to the wild. Walking trails in designated areas allow foot access prohibited in most Kenyan parks. Daily fees for non-resident adults cost 43 US dollars in 2024, with entry gates closing at 1800 hours year-round.
Mount Kenya National Park protects 715 square kilometers around Mount Kenya, Africa's second-highest mountain at 5,199 meters elevation. The park gained UNESCO World Heritage status in 1997 for its afro-alpine ecosystem occurring above 3,500 meters elevation. Point Lenana at 4,985 meters provides the most commonly reached summit, requiring no technical climbing equipment, while Batian peak at 5,199 meters and Nelion peak at 5,188 meters require rock climbing skills and equipment. Approximately 15,000 people attempt to reach Point Lenana annually according to Kenya Wildlife Service figures. The mountain contains 11 small glaciers that have retreated 92 percent since 1899, when their combined area measured 1.6 square kilometers compared to 0.13 square kilometers in 2021. The Kikuyu people consider the mountain sacred and call it Kirinyaga, meaning mountain of whiteness. Forest zones between 2,000 and 3,500 meters contain elephant, buffalo, and black-and-white colobus monkeys. The Sirimon, Naro Moru, and Chogoria routes provide the primary climbing access points.
Lake Nakuru National Park surrounds Lake Nakuru, a shallow alkaline lake in the Rift Valley occupying 188 square kilometers total park area. The lake historically hosted between one and two million lesser flamingos feeding on spirulina algae, creating pink shorelines visible from aircraft. Flamingo numbers fluctuate dramatically based on lake alkalinity and water levels, with counts dropping to fewer than 10,000 birds during high-water periods when dilution reduces algae concentrations. A 75-kilometer electric fence installed in 2011 encloses the entire park. The park contains approximately 100 black rhinos and 70 white rhinos, making it Kenya's largest rhino sanctuary by population density. Rothschild's giraffes were introduced in the 1970s and number approximately 150 individuals. Baboon Cliff on the park's western side rises 200 meters above the lake, providing observation points across the water body. The lake occupies an endorheic basin with no outlet, causing water levels to fluctuate based on rainfall. Park fees for non-resident adults cost 60 US dollars daily in 2024.
