The forests contain a wealth of birds and other animals, like the beautiful bushbuck easily glimpsed in the grades between the ancient cedar trees, or the black and white colobus monkeys climbing along their branches. The interesting geology of the area is reflected in the impressive view of the ash cone and cliff face leading to the summit of Mt. Meru.

Everywhere throughout the Park there are chances to observe the natural world at its own pace, to see different animals in their various habitats and absorb something of the serenity of the surroundings. Those who ascend the summit of the mountain will be rewarded with unparalleled views of the majestic Mt. Kilimanjaro and the Rift Valley.

Three distinct areas are to be found within Arusha National Park: Ngurdoto Crater, the Momela Lakes and the rugged Mt. Meru. The vegetation which occurs in the Park is correlated to the altitude and geology of the area. Ngurdoto Crater is surrounded by forest whilst the crater floor is a swampy area. The Momela Lakes, like many in the Rift Valley, are alkaline, and Mt. Meru is a mixture of lush forests and bare rocks.

Associated with these different vegetation zones and places are different types of animals: migrating water birds settle on the lakes, waterbuck and reedbuck are found near water, while shy bushbuck and duikers keep to the forested areas. Within this wide range of habitats almost 400 species of birds have been recorded in the Park. Some of these are migratory, others are permanently resident in the forests.
