Today, the Serengeti National Park helps protect the greatest and most varied collection of terrestrial wildlife on earth, and one of the last great migratory systems still intact. The Serengeti is the jewel in the crown of Tanzania's protected areas and has come to symbolize paradise. The region encompasses Serengeti National Park, Ngorongoro Conservation Area, Maswa Game Reserve, the Loliondo, Grumeti and Ikorongo Controlled Areas and Maasai Mara National Reserve in Kenya. Two World Heritage Sites and two Biosphere Reserves have been established within the region. It's unique ecosystem has inspired writers and filmakers as well as numerous photographers and scientists. The essential features of climate, vegetation and fauna have barely changed in the past million years. Some patterns of life, death, adaptation and migration are as old as the hills themselves.

An ancient hole in northern Tanzania, Ngorongoro Crater is one of Africa's best wildlife-viewing spots since it acts like a natural cage; the crater's depth makes for a difficult escape for some animals, but most have no need to leave, finding plenty of resources inside. For the traveler, it means not only awesome wildlife viewing, but incredible views from accommodations on the crater's rim. Descend to the crater floor in a four-wheel drive; and once there just cruise around slowly and take in the scene — on any given day see lion, rhino, elephant, buffalo, wildebeest, Thomson's gazelle, zebra, and reedbuck. The small soda lake inside the crater is also the seasonal home of thousands of flamingos.

As you enter Tarangire National Park a vast number of baobabs catch your eye. The gently rolling countryside is dotted with these majestic trees, which seem to dwarf the animals that feed beneath them. The park is spectacular in the dry season when many migratory wildlife species come back to the waters of the Tarangire River. Huge herds of wildebeest, zebras, elephants, eland and oryx gather to stay in Tarangire until the onset of the rains when they migrate again to good grazing areas. Tarangire National Park is second only to Ngorongoro Crater Conservation Area in concentrations of wildlife and lies to the south of the large, open grass plains of southern Maasailand.

Arusha is the safari capital of East Africa, a bustling, vibrant town with the streets filled with 4X4 game viewing vehicles criss-crossing the potholed roads. Maasai warriors in full regalia stroll the streets, mingling with tourists in crisp khaki, fresh off the plane from Europe or the United States.
