Serengeti National Park is a vast treeless plain with millions of animals living here or passing through in search of fresh grasslands. It's most famous for the annual wildebeest migration but you can also see the Big Five here, and nearly 500 species of birds have been recorded on the Serengeti.
As the second largest national park in Tanzania, the Serengeti attracts tens of thousands of tourists each year. The best months for wildlife viewing in Serengeti National Park are between June and September. The wet season is from March to May, with the coldest period from June to October.
The annual migration of over 1.5 million wildebeest and hundreds of thousands of zebras and gazelle takes place in May or early June. This migration is one of the most impressive natural events and the primary draw for many tourists

Located between the Serengeti and Lake Manyara, the Ngorongoro Conservation Area is home to the famous volcanic Ngorongoro Crater and is one of Tanzania's most popular wildlife viewing areas. This huge volcanic crater has a permanent supply of water, which draws thousands of animals who stay in this area rather than migrating.
Visitors come here primarily for viewing large animals and bird watching. Thousands of animals can be seen on the crater floor, including lions, elephants, rhinos, Thomson's gazelles, and buffaloes, but wildebeests and zebras account for over half of the animals that call the Ngorongoro Crater home.
Bird watching is superb, especially around Lake Magadi, which attracts flocks of flamingos to the shallows. Hippos are content to submerge themselves during the day and then graze in the nearby grass in the evening.
The Ngorongoro Crater is the largest intact ancient caldera in the world, nearly three million years old. The Ngorongoro volcano was one of the world's tallest mountains before it exploded and collapsed.

The island of Zanzibar, also called Unguja, is a major holiday destination in Tanzania and known for its beautiful beaches. Part of the Zanzibar archipelago, which consists of the islands of Zanzibar and Pemba, this island has some of the best beaches in the world. The surf varies depending on what side of the island you are on, but visitors will find soft white sand and clear shallow water, along with traditional boats lining the shore.
The historic city of Stone Town, known for old Arabian townhouses, narrow alleyways, and a busy port, is located in the heart of Zanzibar.
