If you are in Kenya, you should pay a visit to the Nakuru National Park. Here lies the Nakuru Lake and this is the most famous bird sanctuary in the country. It is mainly known for its large population of flamingos.
Depending on the water level you can see more than two million flamingos along the shores of Lake Nakuru. You can imagine that this deep pink ribbon along the shore is an impressive sight. The Nakuru Lake has no natural outlet which means that all the collected rainwater has to evaporate. If the water level is too high, it can be that the flamingos go to neighboring lakes Lake Bogoria and Lake Elmenteita. Once the water has evaporated the flamingos come back in large numbers. You can admire over 400 species of birds in the park, so it's the ideal place for bird lovers.
Besides birds, there are also many mammals you can spot in this park. The Nakururu sanctuary protects the Rothschild Giraffe and Rhino. The population of both species has become large, making it ideal place to watch them. Do not forget to admire the northeastern part of the park. People often forget about this part of the park because of the appeal of the flamingos. But here you can see black rhinos, gazelles and zebras. In short: The Nakuru National Park is a must see for every animal lover.
