From Fodor's:
"Tanzania is the quintessential, definitive Africa of your dreams. And who wouldn't want to visit a place where the names of its legendary travel destinations roll off the tongue like an incantation: Zanzibar, Serengeti, Olduvai Gorge, Mt. Kilimanjaro, Lake Tanganyika, Lake Victoria, the Rift Valley, the Ngorongoro Crater, Olduvai Gorge, the Cradle of Humankind.

Great plains abound with legions of game, snow-capped mountains soar above dusty valleys, rain forests teem with monkeys and birds, beaches are covered in sand as soft and white as talcum powder, and coral reefs host myriads of jewel-like tropical fish. Although Tanzania is one of the poorest countries in the world-its economy depends heavily on agriculture, which accounts for almost half of its GDP-it has more land (more than 25%) devoted to national parks and game reserves than any other wildlife destination in the world. Everything from pristine coral reefs to the crater highlands, remote game reserves, and the famous national parks are protected by government law and placed in trust for future generations.

Serengeti is all it's cracked up to be with endless plains of golden grasses (Serengeti means "endless plain" in the Masai language), teeming game, abundant bird life, and an awe-inspiring sense of space and timelessness. Ngorongoro Crater justly deserves its reputation as one of the natural wonders of the world. The ride down onto the crater floor is memorable enough as you pass through misty primeval forest with wild orchids, swinging vines, and chattering monkeys, but once on the floor you could well be in the middle of a National Geographic TV program. You can follow in the footsteps of legendary hunters and explorers when you visit Selous Game Reserve in the south. Although it's the second largest conservation area in the world after Greenland National Park, only 5% of the northern part is open to tourists; but don't worry, you'll see all the game and birds you could wish for with the advantage of seeing it by boat and on foot.

The animals aren't the only wonders Tanzania has to offer. There are the island of Zanizibar, Pemba, and Mafia, as well as Mt. Kilimanjaro, Mt. Meru, and the three great lakes of Victoria, Tanganyika, and Lake Malawi. Wherever you go, you are guaranteed travel experiences that you'll remember for the rest of your life."
