The Nairobi Arboretum occupies 30 hectares and holds over 350 tree species; it is home to over 100 species of resident and migrant birds, a multitude of insects, reptiles and small mammals, notably the playful Vervet and Sykes monkeys. It was a trial plot for fast growing exotic tree species, to meet the high demand of fuel wood required for the newly constructed Kenya- Uganda railway line and thus help save Kenya’s indigenous forests. The Arboretum has been spruced up with paved walkways and park benches and is a suitable place for bird watching, setting up picnic sites as well as relaxing. It’s usually open daily from 9.00am till 5.00 in the evening with entrance charges being 10$ per person.
