5. Olduvai Gorge 
Olduvai Gorge, the archaeological site also known as "The Cradle of Mankind”, is a steep-sided ravine in the Great Rift Valley that stretches through eastern Africa. It is in the eastern Serengeti Plains in northern Tanzania and is about 48 km (30 mi) long. It is located 45 km from the Laetoli archaeological site. The name is a misspelling of Oldupai Gorge, which was adopted as the official name in 2005. Oldupai is the Maasai word for the wild sisal plant Sansevieria ehrenbergii, which grows in the gorge.
Olduvai Gorge is one of the most important prehistoric sites in the world and has been instrumental in furthering the understanding of early human evolution. This site was occupied by homo habilis approximately 1.9 million years ago, Paranthropus boisei 1.8 million years ago, and Homo erectus 1.2 million years ago. Homo sapiens are dated to have occupied the site 17,000 years ago.
This site is also significant in showing increased developmental and social complexities in hominins. Evidence of this is shown in the production and use of stone tools, which indicates the increase in cognitive capacities. There is also evidence indicating the practices of both scavenging and hunting,  which is highlighted by the evidence of gnaw marks predating cut marks,  and comparisons on percentages of meat versus plant in the early  hominid diet. Furthermore, the collection of tools and animal remains in  a central area is evidence of increases in social interaction and communal activity.

    6. Ngorongoro Crater
The famous Ngorongoro Crater is a World  Heritage Site situated at the eastern edge of the Serengeti in northern  Tanzania. The crater is the largest unbroken ancient caldera in the  world. Nearly three million years old, the once-volcanic Ngorongoro is  now considered “Africa’s Garden of Eden” – a haven for thousands of wild  game, including lions, elephants, wildebeests, zebras, rhinos,  Thomson’s gazelles and buffaloes.

The crater is ringed with steep walls  and shelters forests, grasslands, fresh springs and a large soda lake at  its centre. The Ngorongoro volcano before it exploded and collapsed 2  million years ago, was one of the world’s tallest mountains. The crater  measures about 19 kilometres (12 miles) across and the rim is 600 metres  (2,000 feet) above the crater floor.

Buffalo, elephant, giraffe and warthog are easily  seen in Manyara Park and the lakeshore boasts over 400 species of water  bird such as flamingo, pelican, sacred ibis and Egyptian geese.
Serengeti National Park
One of the new Seven Wonders of the World, the seemingly endless plains  of Serengeti National Park are dotted with kopjes, rivers and woodland.  The huge herds of wildebeest and zebra can be viewed in special areas of  Serengeti during different times of the year. 
Witness the daily drama of life and death in Serengeti, where lion,  cheetah, leopard and other predators hunt among enormous herds of  gazelle, eland, buffalo and other beasts. Watch out for the smaller  beauties – caracal, serval cat, genet and bat-eared foxes.  Let the  circling and descending vultures guide you to the site of a recent kill.
Ngorongoro Crater & Conservation Area
Ngorongoro Crater - the largest unbroken caldera in the world – contains  an extraordinary number and variety of animals within its 610 m high  walls and around its central soda lake.  Countless flamingo, crowned  cranes and secretary birds make their long-legged way among the grazing  gazelle, rhino, elephant, wildebeest, zebra and other species too  numerous to mention here. 
Take a guided walk in the magnificent Ngorongoro Highlands through  forests and around Olmoti and Empakaai Craters. Drive across to Olduvai  Gorge and learn about the origins of mankind; marvel at the remains of  prehistoric elephant, giant-horned sheep and enormous ostrich which  inhabited the plains alongside our earliest ancestors. 
Tarangire National Park
Famous for its huge herds of elephant, Tarangire Park also boasts the  always-flowing Tarangire River, which attracts thousands of animals from  the parched Masai steppe during the dry season months of August and  September.  Search for hunting lion in the grassland, examine tree  branches for the hanging tail of a sleeping leopard, marvel at  long-necked gerenuk and fringe-eared oryx among the ancient baobabs and  strange sausage trees which spread their shade around this wonderland of  a national park. 
Selous Game Reserve
Selous Game Reserve is another World Heritage Site and the largest  protected wildlife area in Africa.  Here you can search for rare Sable  Antelope and packs of African Wild Dogs – lycaon pictus – the painted  wolf. Here you can take a boat safari on the Rufiji River, amongst  hippo, crocodile and numerous water birds. Drive slowly through the grassland plains, savannah woodland and rocky  outcrops, in the company of bushbuck, duikers, eland, hartebeest, hyena,  klipspringer, impala, giraffe, oryx, reedbuck, waterbuck and zebra.   Watch belligerent yellow baboons, gentle black and white colobus, vervet  and blue monkeys, moving among the prolific birdlife of this vast  stronghold of nature. 
Ruaha National Park
Visit Ruaha park and and take a boat safari down the Great Ruaha River.  Now bigger than Kruger park in South Africa and second only to Zambia’s  Kafue park, Ruaha supports enormous concentrations of wildlife and a  wide variety of birdlife. 
Game viewing in Ruaha starts as your plane taxies in; long-legged  giraffe race beside the airstrip, closely followed by cantering zebra  while primordial pachyderms loiter in the shade of ancient baobab trees.   At the last count, this park boasted of almost 10,000 elephants. 
Mikumi National Park
Mikumi is the most easily accessible of Tanzania’s southern parks.   Covering some 3,230 sq km of wilderness, Mikumi is yet another animal  kingdom where wildlife has the right of way and nature alone holds sway.    Discover the abundant wildlife of Mkata Floodplain, where lion kings  survey their domain from the flattened tops of termite mounds.  Marvel  at the sheer size and power of eland – the world’s largest antelope –  and at the poetry-in-motion of greater kudu and sable antelope. 
Katavi National Park
Best in the dry season months of  June through October, when the Katuma  River and floodplains form the only source of drinking water for miles  around, this isolated wilderness area boasts 4,000 strong herds of  elephant, 1,000-plus buffalo, numerous giraffe, zebra, impala and  reedbuck. 
Add to the above numerous prides of lion, clans of spotted hyena, up to  200 hippos in one small pool and myriad colourful birds and you will  have an idea of the spectacular tapestry of nature to be found in  Katavi. 
Kitulo National Park
One of the great floral spectacles of the world, Kitulo has been dubbed  by botanists “the Serengeti of Flowers” and is called “God’s Garden by  the local inhabitants. The breathtaking scale and diversity of Kitulo’s  wildflowers include a multitude of orchids, stunning red-hot poker,  aloes, proteas, lilies and aster daises.
Kitulo, perched at around 8,500 ft, is the first national park in  tropical Africa to be gazetted largely for its floral significance, and  is a riot of color during the rainy months of late November to April. 
Udzungwa Mountains National Park
Often called the African Galapagos, for its treasure-trove of endemic  plants and animals,  Udzungwa is the largest (and most bio-diverse) of a  chain of large forest-clad mountains which rise regally from the flat  coastal scrub of Eastern Tanzania and which are known collectively as  the Eastern Arc Mountains.
This brooding and primeval rainforest, which sustains rare plant species  not found elsewhere in the world, hides waterfalls, exceptional forest  birds and the newly-discovered Sanje crested mangabey.
Saadani National Park
Saadani is a coastal wildlife sanctuary where beach meets bush in an  environment beyond compare.  Relax on the palm-fringed white sands of  the Indian Ocean where lion and elephant leave their footprints and  observe one of the last major green turtle breeding sites on mainland  Tanzania. 
Take a game drive or a guided walk in the bush or visit Saadani fishing  village, where a collection of ruins pays testament to its 19th century  heyday as a major trading port. 
Gombe National Park
A scheduled flight to Kigoma and a boat across Lake Tanganyika brings  you to Gombe Stream – a fragile strip of chimpanzee habitat straddling  the steep slopes and river valleys of Lake Tanganikya’s sandy northern  shores. 
Made famous by the pioneering work of Dr Jane Goodall, the Gombe chimps  are habituated to human visitors and thus are easy to follow and  observe.  Share the beach with a troop of friendly olive baboons to the  harsh cry of Africa’s iconic fish eagle.
Mahale Mountains National Park
Deep in the heart of the African interior lie the Mahale Mountains, home  to some of Africa’s last remaining wild chimpanzees.  Trekking these  chimps through montane rainforest and high grassy ridges chequered with  alpine bamboo is an unparalleled experience.
After your trek, you can swim and snorkel in the impossibly clear waters  of the world’s longest and second-deepest freshwater lake. Take a boat  and try your luck with some of the estimated 1,000 fish species which  inhabit the lake.
Rubondo Island National Park
Take a boat ride to Rubondo Island – a water wonderland, tucked into the  southwest corner of Lake Victoria. Listen to the voice of Africa in the  ear splitting, evocative duet of fish eagles, watch yellow-spotted  otters frolicking in the island’s rocky coves.
Other activities which can be undertaken on Rubondo Island are chimp  trekking, bird-watching excursions, sport fishing and tracking the  aquatic sitatunga in the papyrus swamps. 
      8. Mineral Deposits
|  | 
| Mineral Deposits Map | 
Tanzania has a great potential particularly for gold, base  metals, diamonds, ferrous minerals and a wide variety of gemstones,  including the world renowned Tanzanite (blue zoisite) occurring in the  Proterozoic metamorphic rocks of the Usagaran and Ubendian Systems.
Other gemstones mined in the country include ruby, rhodolite,  sapphire, emerald, amethyst, chrysoprase, peridot and tormaline.  Recently, a major alluvial occurrence was discovered in the southern  region of Ruvuma, Mtwara and Lindi. Varieties include chrysoberyl,  spinels, sapphire, garnets, zircons and diamonds.
Coal, uranium, and various industrial minerals such as soda, kaolin,  tin, gypsum, phosphate and dimension stones are plentiful. Coal  resources similar in quality to the Gondwana coals of southern Africa  occur in the Ruhuhu and Songwe-Kiwira basins in
Limestone and dolomite-good resources of high purity occur in the  white marble deposit of the Morogoro Region. Potential for dimension  stone and refractory grade limestone is therefore excellent.
A variety of clays - bentonite, kaolin and fullers earth - in  size-able deposits have been identified and are only scantily exploited.  The Pugu kaolin deposit located some 30 kms West of Dar es Salaam has a  great potential for development.
Evaporates and saline deposits of economic significance are  associated with the rift valley lakes. Investigations of the Soda ash  deposits at Lake Natron revealed a potential recovery of over one  million tonnes a year.
Graphite occurs in high-grade gneisses mainly in the Usagaran system.  Sufficient reserves have been identified at Merelani, northern  Tanzania, for a 40 year operation at a mining rate of 15,000 tonnes per  year of high grade flake graphite of 97-98% purity.
Basemetals are found in a belt running from Kagera through Kigoma to  Mbeya, Ruvuma and Mtwara regions: recent evaluations have so far  outlined contained resources of 500,000 tonnes nickel, 75,000 tonnes  copper and 45,000 tonnes cobalt.
Gold and diamonds have always been the mainstay of the country's  mineral production. In fact Tanzania has been a significant diamond  producer for several decades, with the bulk of production coming from  the Mwadui area where commercial production began in 1925. But gold is  the resource currently offering one of the best areas for investment.  The current perceived opportunities range from former mines in the  Archaean Greenstone belts around Lake Victoria, Proterozoic rocks and  conceptual grass root plays in Karoo and younger rocks. Investigation  has mainly been focused on the greenstone belts around Lake Victoria  with particular attention on the shear hosted gold mineralization  associated with banded iron formations (BIF), tufts and  volcano-sedimentary exhalatives. Several "world class" gold deposits  have already been discovered in the Lake Victoria Goldfields and are at  different stages of development. These deposits have reached various  stages of development.
    9. Indian Ocean and Lake Ports
Indian Ocean ports are Dar es Salaam, Mtwara, and Tanga; minor seaports serving coastal traffic include Lindi, Kilwa Masoko, Mafia Island, Bagamoyo, Pangani and Kwale
The principal port of Tanzania is Dar es Salaam,  handles 95% of the country's international sea trade. The port serves the landlocked countries of Malawi, Zambia, Democratic  Republic of Congo, Burundi, Rwanda and Uganda. The port is strategically  placed to serve as a convenient freight linkage not only to and from  East and Central Africa countries but also to middle and Far East,  Europe, Australia and America.

 10. World Heritage Sites
Tanzania has a long history of tribal habitation stretching back at  least 10,000, to the early hunter-gatherers who lived around Olduvai  Gorge. Later tribal migrations, occurring between 3,000 to 5,000 years  ago, brought agricultural and pastoral knowledge to the area as  competing tribal groups spread over the country in search of fertile  land and plentiful grazing for their herds. European Missionaries and  explorers mapped the interior of the country by following well-worn  caravan routes, including Buron and Speke who in 1857 journeyed to find  the source of the Nile. Traditional ways of life remained largely intact  until the arrival of German Colonizers in the late 19th Century.
 Engaruka
Mysterious ruins of complex irrigation systems span  the area around Engaruka, the remnants of a highly developed but  unknown civilization that inhabited the area at least 500 years ago-and  then vanished without a trace.
Kilwa Kisiwani
The  Island of Kilwa kisiwani and the nearby ruins of Songo Mnara are among  the most essential remnants of Swahili civilization on the East African  Coast. The area became the center point of Swahili civilization in the  13th Century, when it controlled the gold trade with Sofala, a distant  settlement in Mozambique in the 14th Century, Arab traveler Ibn Battuta  described Kilwa as being exceptionally beautiful and well-developed.  After a brief decline under the rule of the Portuguese, Kilwa once again  became a center of Swahili trade in the 18th Century, when slaves were  shipped from its port to the islands of Comoros, Mauritius and Reunion.
Lindi
The  port town of Lindi, in south-western Tanzania, was the final stop for  slave caravans from Lake Nyasa during the heyday of the Zanzibar’s  Sultans. In 1909, a team of Germans paleontologists unearthed the  remains of several dinosaur bones in Tendunguru, including the species  Brachiosaurus brancai, the largest discovered dinosaur in the World.
Mikindani
Another  central port in the Swahili coast’s network of Indian Ocean trade, in  the 15th Century Mikindani’s reach extended as far as the African  hinterlands of the Congo and Zambia. The area became a centre of Germany  colonial administration in the 1880s and was a chief exporter of sisal,  coconuts, and slaves.
Tanzania is a country which encompasses an          extraordinary history and an abundance of          natural wonders; therefore it is no surprise          Tanzania has eight World Heritage Sites. These          chosen sites are a fundamental reminder why          interaction between people and nature must          achieve a balance of preservation and          conservation between the two. 
"The Serengeti National Park is Tanzania’s          oldest park, and one of the world’s last great          wildlife refuges, hence its World Heritage Site          status." 
        
Kilimanjaro National Park
The Kilimanjaro National Park is located near          Moshi, Tanzania. It is centered on the iconic          and dramatic snow- clad slopes of Mount          Kilimanjaro, which covers an area of 753 km (291          square miles). In 1973 , the mountain above the          tree line was classified as a National Park and          was opened to public access in 1977 , but it          wasn’t until 1987 the park became listed as a          World Heritage Site by UNESCO.
Stone Town, Zanzibar
Stone Town or Mji Mkongwe in Swahili meaning          “ancient town”, is the old part of Zanzibar          City. The old town is built on a triangular          peninsula of land on the western coast of the          island and was awarded World Heritage Site          status in 2000 . Justification for the          inscription, includes, its rich cultural fusion          and harmonization; its great symbolic importance          in the suppression of slavery; and the intense          seaborne trading activity between Asia and          Africa, which is illustrated today in the          exceptional architecture and urban structure of          the Stone Town.
The Ngorongoro Conservation Area
The Ngorongoro Conservation Area (NCA) boasts          the finest blend of landscapes, wildlife, people          and archaeological sites in Africa and is          situated 180 km west of Arusha. The rich pasture          and permanent water of the Crater floor supports          a large resident population of wildlife of up to          25 ,000 - predominantly grazing animals. The          conservation area is administered by the          Ngorongoro Conservation Area Authority, and its          boundaries follow the boundary of the Ngorongoro          Division of Ngorongoro District. It covers an          area of 8,288 km (3,200 square miles).
Selous Game Reserve
The Selous Game Reserve covers a total area of          54,600 km (21 ,081 square miles) and is one of          the largest fauna reserves of the world, located          in the south of Tanzania. It was designated a          UNESCO World Heritage Site in 1982 due to the          diversity of its wildlife and undisturbed          nature. The reserve is home to typical savannah          animals such as elephants, hippopotami, the rare          African Wild Dog and crocodiles, which are all          found in larger numbers compared to any other          African park. 
Serengeti National Park
The Serengeti National Park is Tanzania’s oldest          park, and one of the world’s last great wildlife          refuges, hence its World Heritage Site status.          It is most famous for its annual migration of          over one million white bearded (or brindled)          wildebeest and 200 ,000 zebra. The park covers          14,763 km (5,700 square miles) of grassland          plains and savanna as well as riverine forest          and woodlands. The park lies in the north of the          country, bordered to the north by the national          Tanzania and Kenyan border, where it is          contiguous with the Masai Mara National Reserve. 
Kondoa Rock Art Sites
The Kondoa rock art site is a series of caves          carved into the side of a hill looking out over          the steppe. The cave site is nine kilometres off          the main highway from Kondoa to Arusha, about 20          km north of Kondoa. The site has a spectacular          collection of images from over 150 shelters          depicting elongated people, animals, and hunting          scenes. Today many of the shelters are still          considered to have ritual associations with the          people who live nearby, reflecting their          beliefs, rituals and cosmological traditions. 
Ruins of Kilwa Kisiwani and Ruins of Songo          Mnara
The remains of two great East African ports          admired by early European explorers are situated          on two small islands near the coast. From the 13          th to the 16 th century, the merchants of Kilwa          dealt in gold, silver, pearls, perfumes, Arabian          crockery, Persian earthenware and Chinese          porcelain; much of the trade in the Indian Ocean          thus passed through their hands. Serious          archeological investigation began in the 1950 s.          In 1981 it was declared a World Heritage Site,          and noted visitor sites are the Great Mosque,          the Mkutini Palace and some remarkable ruins.          However, the ruins are also on the List of World          Heritage in Danger. The list constitutes a call          to improve their safeguarding and is designed to          rally national and international efforts for          their preservation.
