Ngorongoro Crater is the largest and the best preserved volcanic caldera in the world. Because of "the natural enclosure", it forms its own ecosystem and even has its own weather.

Every year, there are about 2 million wildebeests, Zebras and other animals migrating around Serengeti plains, covering more than 1000 miles. They have been doing this for more than a million years.

Vast, diverse and live. This is the world famous Serengeti National Park.

Northern Tanzania is just full of wonders. Between Ngorongoro and Serengeti, Oldupai Gorge is one of the most important paleoanthropology sites that answers the question, "where did mankind originate?"

Although the tribe visit might be staged, we got a chance to have a fleeting view on how Tanzanians live in the rural area near Lake Eyasi.

At Lake Manyara, I finally corrected my misunderstanding about East African Rift Valley - there is no valley, but more like a long cliff.

Although not as famous as Serengeti, Tarangire National Park has the most diverse landscape, vegetation and wildlife in Tanzania's northern safari circuit.

Arusha National Park offers good hike trails to dominating Mt. Meru, access to the dramatic landscape created by the eruption of the volcano, and plenty of opportunities to view wildlife.

After spending almost 24 hours flying, we finally arrived at the starting point of our journey, Arusha.
