Most Gulf passports need a visa for Tanzania. Apply on the official e-visa site (visa.immigration.go.tz) before you fly, and check the rules for your nationality.
Mandatory insurance
Visitors arriving in Zanzibar must buy the government inbound travel insurance at inbound.visitzanzibar.go.tz: US$44 for adults, US$22 for children aged 3–17, free under 3. Your own insurance does not replace it.
Yellow fever
A vaccination certificate is required if you arrive from, or spend more than 12 hours in transit in, a country with yellow fever risk.
Health
Malaria and dengue are present. See a travel clinic at least eight weeks before you go and follow official advice on vaccines and malaria tablets.
Use reputable taxis
Book through your hotel or a known operator, and don’t accept lifts from strangers.
Dress modestly
Cover shoulders and knees away from the beach, especially in Stone Town and villages.
Mind the tides
The east coast lagoons drain far at low tide; check a tide table for swimming, and wear reef shoes on coral and rock.
Carry cash
Shillings for markets and small shops; US dollars are widely quoted for tours and fees. Cards work in larger hotels.
Protect valuables
Bag snatching happens in Stone Town and on beaches. Carry a copy of your passport and avoid walking alone at night.
Tipping
Not compulsory. A tip for guides, boat crews and good service is appreciated if you were happy.
Drink bottled water
Use bottled or filtered water and carry plenty; January is hot and humid.
Ask before photos
Ask before photographing people, especially women and in villages.
Zanzibar is welcoming and generally relaxed. Check your government’s travel advice, buy the mandatory insurance and confirm entry rules for your passport before you travel.
