Tanzania's cultural experiences range from the UNESCO-listed urban heritage of Zanzibar's Stone Town to the living ceremonial traditions of the mainland's 120 ethnic communities. Guided tours of Stone Town's carved door streets, former slave market Anglican cathedral, and spice plantations are best done with a local Swahili cultural guide. Makonde wood sculpture studio visits in Dar es Salaam, traditional Maasai community cultural experiences in the northern circuit, and dhow boat-building demonstrations in Bagamoyo extend the programme. Guided visits to the National Museum's Olduvai Gorge fossil collection and the Zanzibar Palace Museum of sultanate history provide the historical framework. Tours by local guides can bring the whole thing into focus.
