Ernest Hemingway remarked that this park had the loveliest lake in Africa, and he may have been right. Manyara Lake is really stunning. It covers one-third of the park size, and despite its high salt content, it is safe for animals to drink so it remains an essential life source for many animals in the area. It is also the main hangout spot for wild flocks of flamingos, and other bird life. However, truly unique to Lake Manyara National Park is their resident tree-climbing lions. Researchers have still not come to a conclusion as to why these lions habitually laze among the treetops, but nevertheless, it is an extraordinary sight to see.
