Best visited early in the morning, Watamu Marine National Park is the United Nations Biosphere Reserve and one of the oldest and best snorkeling areas on the coast. It is 4.2km from Watamu town. With over 600 fish species, the clear waters make spotting them stress-free and there are higher chances of spotting dolphins with ease than Wasini in Diani. It’s the best-protected coral reef along Kenya’s entire coastline, and diving in the warm, clear water gives you a glimpse into this underwater world.You can also take a boat trip or even swim out to the reef at low tide. Look out for green, hawksbill, and olive ridley turtles, which nest on Watamu’s main beach between April and October. The coral itself is also a highlight, with over 150 species of hard and soft corals thriving here, including cerebral-looking brain corals, delicate fan corals, and sponges. The entry fee is Ksh 200 per adult and Ksh125 per child but you can negotiate the boat ride prices with the vendors.
