When you travel to Tanzania, the best places to visit and enjoy a safari include Katavi, Selous, Ruaha, Tarangire, Ngorongoro and Serengeti where you can witness the great annual migration of millions of wildebeest. Some of the best beaches on earth can be found in Zanzibar and Mafia Island. You can hike up Africa's tallest mountain, Mount Kilimanjaro. Other incredible mountains include Mahale, where you can visit the largest remaining population of chimpanzees in the wild. The islands of Kilwa Kisiwani and Songo Mnara bear exceptional testimony to the expansion of Swahili coastal culture, the lslamisation of East Africa and the extraordinarily extensive and prosperous Indian Ocean trade from the medieval period up to the modern era.
