Creatures In Trees Of The Nairobi National Park! There is something mysterious and wondrous about being in a natural forest irrespective of where you are in Africa, and the Nairobi National Park is such a wonderful place. The thick bush is a hiding place for many species, including some rarely seen species. Driving slowly along some of the many narrow roads through the forest, often causes me to have a feeling that there could be a special sighting at any moment. Especially when looking up into the trees, we have had so many sightings over the years of creatures in the trees. They range from insects to reptiles, to monkeys and baboons, to big cats as well.
