Watamu Marine National Park , located about 140 km north of Mombasa, Kenya, was established in 1968 as one of the country’s first marine parks. Its coral gardens lie just 300 metres offshore and host around 600 species of fish, 110 species of stony coral, and countless invertebrates, crustaceans, and molluscs. Water temperatures range from 20°C between June and November to 30°C from December to May. In 1979, the park was designated a UNESCO Biosphere Reserve, highlighting its global ecological importance.
The park was created alongside Malindi Marine National Park in 1968 by the Kenyan government. Today, Watamu forms part of a UN-recognised World Biosphere Reserve, reflecting its role in marine conservation and biodiversity protection.
Watamu’s coral reefs are the backbone of its ecosystem, supporting over 150 species of hard and soft corals such as brain corals, fan corals, and sponges. These reefs provide nutrients for a rich variety of marine life, with more than 500 fish species in the park and over 1,000 in the wider reserve. Larger species include whale sharks, manta rays, octopus, and barracuda.
The park is also a vital nesting site for endangered sea turtles. A turtle watch program has secured the main beach as a 99% viable nesting ground for green, hawksbill, and olive ridley turtles. Leatherback turtles do not nest here but migrate through nearby waters.
Watamu’s reefs suffered severe bleaching between 1997 and 1998, leading to high coral mortality. Recovery has been slower than average, with urbanization, tourism, agriculture, and deforestation contributing to further degradation. Loss of mangroves, overfishing, and coastal development have threatened the marine ecosystem, which includes coral reefs, mangrove forests, and seagrass beds.
To address these challenges, land-use planning was integrated into park management, focusing on habitat protection for marine species and stricter enforcement of environmental laws. The park’s creek serves as a spawning ground for fish, a wintering site for migratory waders, and a feeding area for sea turtles.
Local conservation groups, such as Watamu Turtle Watch, run programs that pay fishermen to tag and release turtles caught accidentally. Volunteers record data, rehabilitate sick turtles, and run adopt-a-turtle initiatives. Fishermen are allowed to fish in the reserve using traditional methods and targeting permitted species, balancing conservation with community livelihoods.
Snorkeling and Diving: Explore coral gardens teeming with fish and marine life.
Glass-Bottom Boat Rides: View underwater ecosystems without getting wet.
Turtle Watching: Observe nesting and hatching turtles, especially at monitored beaches.
Birdwatching: Spot migratory waders and coastal birds around the creek.
Marine Education Tours: Learn about conservation efforts and turtle rehabilitation programs.
Fishing (in the reserve): Traditional, regulated fishing allowed for local communities.
The dry season, from December to March and July to October, offers the best conditions for snorkeling, diving, and turtle watching, with calm seas and clear visibility. The wetter months, April to June and November, bring lush coastal scenery and fewer tourists, though sea conditions may be rougher.
Visitors should bring snorkeling gear, reef-safe sunscreen, hats, and plenty of water. Glass-bottom boat tours are ideal for families or those not comfortable swimming. Respect conservation rules by avoiding coral contact and supporting local eco-programs. Early mornings are best for turtle watching, while afternoons provide excellent light for photography. Staying in Watamu village offers easy access to the park and opportunities to engage with local conservation groups.
