Tanzania joins two rarely-paired wonders: Zanzibar — the spice island Omanis ruled for centuries and made their sultanate's capital (a complete Arab story waiting in Stone Town's lanes) — and Serengeti-Ngorongoro, Earth's greatest safari stage. Easy e-visa/VOA for Saudis; ~6-7h via the Gulf; June-October is the golden dry (safari and beaches together); overwhelmingly Muslim Zanzibar makes halal the default and the adhan the day's frame — complete ease for Gulf families.
