Tarangire National Park, though less famous then the well-known Serengeti, is no less a spectacular destination. Because of its year-round water supply, the Tarangire River Valley becomes packed with wildlife during the dry season. The park has one of the highest population densities of elephants anywhere in Africa, and its ancient baobab and numerous acacia trees make it a beautiful and unique place. Other common animals are tree climbing lions, zebra, wildebeest, waterbuck and giraffe. Tarangire is a popular stop for safaris traveling the northern safari circuit on their way to Ngorongoro and the Serengeti. Since Tarangire is relatively small, it is also excellent for day trips from Moshi. The park is bordered by two game reserves and the wildlife moves freely throughout.
