Nairobi is one of the few cities in the world with a national park within its boundaries, making it a prime tourist destination as well, with several other tourist attractions. The most famous is the Nairobi National Park, the only game reserve of this nature to border a capital city, or any major city. The park contains many animals including lions, giraffes, and black rhinos. The park is home to over 400 species of birds. The Nairobi Safari Walk is a major attraction to the Nairobi National Park as it offers a rare on-foot experience of the animals.
