Aberdare National Park.

Aberdare National Park rises into a mist-shrouded world of highland forest, bamboo thickets, and open moorland along the Aberdare mountain range, a striking contrast to Kenya's better-known savannah parks. Famous "tree hotels" perched over floodlit waterholes let visitors watch elephant, buffalo, and the elusive black leopard emerge from the forest after dark, while the park's rivers tumble over dramatic waterfalls such as the Gura and Chania Falls. Cooler temperatures and lush, dense vegetation make this a refreshingly different high-altitude safari experience within easy reach of Nairobi.
