Watamu Marine National Park was Africa’s first marine national park — and it’s still one of the best places on the continent to combine reef diving, sea turtle conservation, and whale shark encounters in one trip. On Kenya’s Indian Ocean coast, just north of Mombasa, it pairs naturally with the nearby Arabuko-Sokoke Forest for a complete coastal wildlife extension to a mainland safari. Explore our Kenya safaris to add a Watamu coastal extension.

Africa’s First Marine National Park
Watamu Marine National Park and Reserve, on Kenya’s Indian Ocean coast in Kilifi County, holds a special place in African conservation history as the continent’s first marine national park, established in 1968. More than fifty years on, it remains one of the most biologically rich stretches of coastline in East Africa, protecting a fringing coral reef, important sea turtle nesting beaches, and a seasonal whale shark aggregation, all within easy reach of Mombasa.
The reef itself runs for miles along the Watamu-Malindi coastline, its outer edge dropping away into deeper water where currents draw in larger pelagic species like manta rays and tuna. Coral cover here has been through cycles of bleaching and recovery over the years — a familiar story for reefs worldwide as ocean temperatures rise — but Watamu’s reef remains home to several hundred species of reef fish and well over 200 species of hard coral, making it one of the richest single sites for marine biodiversity on the Kenya coast.
Sea Turtles: From Nest to Ocean
Watamu’s beaches are an important nesting site for three species of sea turtle — green, hawksbill, and olive ridley — with the nesting season running roughly October through March. Watching a female green turtle nest is one of the most moving wildlife experiences on the Kenya coast: a turtle weighing well over 100kg hauls herself up the beach at night, digs a chamber with her hind flippers, lays over a hundred eggs, and carefully disguises the site before returning to the sea, the whole process taking a couple of hours from start to finish.
Roughly two months later, the buried eggs hatch almost simultaneously, and the hatchlings dig their way to the surface together as a group — a single hatchling isn’t strong enough to move through the sand alone, so the whole clutch works together over a couple of days before emerging in a synchronised rush. From there, they orient toward the brightest horizon, historically moonlight and starlight over the ocean, though coastal development and artificial lighting have made this more complicated in recent years. Local conservation groups run night patrols and, where needed, relocate at-risk nests to protected hatcheries to give hatchlings the best possible chance.
Whale Sharks Offshore
Watamu’s outer reef also draws whale sharks, the world’s largest fish, during seasonal windows when upwelling currents bring plankton blooms close to the surface. These enormous filter feeders, sometimes reaching well over 10 metres in length, glide slowly through the water feeding on plankton, offering snorkelers a genuinely awe-inspiring close encounter in clear, warm water.
Whale shark encounters are tightly regulated to protect both swimmers and sharks — operators limit group sizes, enforce a minimum viewing distance, and prohibit touching, ensuring the experience stays sustainable as visitor numbers grow. Boat trips out to the aggregation area during peak season offer a strong chance of an encounter, sometimes with several individual sharks visible in the same stretch of water.
Beyond the Reef: Mida Creek and Arabuko-Sokoke
Just south of the main park, Mida Creek’s mangrove channels are worth a visit in their own right, home to a small, elusive population of dugongs among the seagrass beds, along with excellent birdwatching among the mangroves. Nearby, Arabuko-Sokoke Forest Reserve, the largest remaining coastal forest in East Africa, adds a completely different habitat to the trip, home to several bird species found almost nowhere else in Kenya, including the tiny, globally threatened Sokoke scops owl.
Planning Your Visit
Watamu makes an excellent multi-day coastal extension to a mainland Kenya safari, combining time on the reef with visits to Mida Creek and Arabuko-Sokoke Forest. Accommodation ranges from classic beachfront lodges with established marine safari operations to smaller camps focused on turtle conservation or mangrove ecology, depending on which side of Watamu’s wildlife most appeals to you.
Frequently Asked Questions
When is turtle nesting season at Watamu?
Turtle nesting runs roughly from October to March, with green, hawksbill, and olive ridley turtles all nesting on Watamu’s beaches during this period.
When is the best time to see whale sharks at Watamu?
Whale sharks aggregate seasonally when upwelling currents bring plankton close to the surface, with the best chances typically in the November to January and February to April windows.
Can Watamu be combined with a mainland Kenya safari?
Yes. Watamu makes a natural coastal extension to a Masai Mara or other mainland safari, easily combined with a visit to nearby Arabuko-Sokoke Forest.
Why is Watamu historically significant for conservation?
Watamu Marine National Park was Africa’s first marine national park, established in 1968, and remains one of the continent’s most important marine protected areas.
