Head out by boat on Lake Naivasha, one of the best ways to feel the quiet richness of this freshwater ecosystem. With an experienced local guide, look for hippos, kingfishers, fish eagles, herons, giraffes, zebras and waterbucks along the shore. The lake sits below the Eburru volcanic range and is framed by acacia trees. Afterward, the day is free. You might visit Hell's Gate National Park, hire a bike or join a guided walk in Crater Lake Game Sanctuary.
