Kiunga Marine National Park contain a diversity of landscapes, seascapes, mangroves, mudflats, lagoons, sand dunes, beaches, sand islands, raised reef islands, sea-grass beds, and coral reefs.
It is the biggest mangrove stand in Kenya with the tallest mangrove trees reaching 30 meters high.
The reserve’s location at the convergence of two major ocean currents creates unique ecological conditions that nurture three inter-dependent marine habitats; mangroves, sea grass beds and coral reefs.
The coral reefs found within Kiunga are comprised of mainly patch reefs, with fringing reefs in the northern part.
Vegetation includes Microscopic marine plants and dugong grass, coastal scrubland and mangrove swamps.
