This strip of sand is 50 km (31 mi) northeast of Lamu. The main attraction of Kiwayu Island is its proximity to Kiunga Marine National Reserve, a marine park encompassing Kiwayu Bay. The confluence of two major ocean currents creates unique ecological conditions that nurture three marine habitats—mangroves, sea-grass beds, and coral reefs. Here you have a chance of catching a glimpse of the most endangered mammal in Kenya, the manatee. Because of its tasty flesh, this gentle giant has been hunted to near extinction all along Africa's eastern coast. The best way to get here is to charter a dhow from Lamu. If you can muster a group of six people, it should cost you about US$20–US$30 per person including food, water, and snorkeling equipment. Otherwise, your lodge or hotel will arrange the trip for you; it's 90 minutes by speedboat.
