Where is Zanzibar?

Zanzibar is a semi-autonomous archipelago in the Indian Ocean, part of the United Republic of Tanzania, sitting off the Swahili Coast of East Africa. If you're trying to place it on a map for the first time, or figure out how it relates to "Tanzania" and "the Serengeti" as separate names you've heard, this page untangles the geography.

The short answer

Zanzibar lies in the Indian Ocean roughly 25–50 km off the coast of mainland Tanzania, opposite the port city of Dar es Salaam. It sits just south of the equator, at a latitude that gives it a warm, humid, tropical climate year-round. It is not a separate country — it's a semi-autonomous part of Tanzania, with its own government (the Revolutionary Government of Zanzibar) handling many internal matters, while defence, foreign affairs, and some other functions are handled at the union level with the mainland.

Zanzibar, Unguja, and Pemba — the naming that confuses people

"Zanzibar" technically refers to the whole archipelago, but in everyday travel use it almost always means Unguja, the main and much larger island where Stone Town, the international airport, and virtually all the well-known beach resorts are located. Pemba, the second main island, lies further north and sees far fewer tourists, known more for diving, cloves, and a quieter, less developed feel. Unless a hotel or tour specifically says "Pemba," everything discussed across this site — beaches, Stone Town, spice tours — refers to Unguja.

How Zanzibar relates to mainland Tanzania and the Serengeti

This is the geography question that matters most for planning a combined trip. Mainland Tanzania is the much larger landmass to the west, home to the Serengeti National Park, Ngorongoro Crater, Kilimanjaro, and the rest of the country's famous safari circuit — all a significant distance inland and to the north of Zanzibar, not adjacent to it. Zanzibar itself has no safari wildlife of its own in the way people picture "Africa safari" scenes (see our Is There a Safari in Zanzibar? page for the full explanation) — the island is a beach and cultural-heritage destination, and the Serengeti is reached by flying inland, typically via Arusha or directly to a Serengeti airstrip.

Place	Distance/time from Zanzibar
Dar es Salaam (mainland)	~20-minute flight, or a few hours by ferry across the Zanzibar Channel
Arusha (safari gateway town)	Around 1.5–2 hours by scheduled light aircraft
Serengeti National Park (fly-in)	Typically 2–3 hours total including any stop, depending on route and specific airstrip
Kilimanjaro (for climbers)	Usually reached via Kilimanjaro International Airport near Arusha/Moshi, a separate onward connection from Zanzibar

Regional context

Zanzibar sits within East Africa, in the same broad region as Kenya (to the north) and Mozambique (to the south), and is often combined by travellers with a Kenya safari (Maasai Mara) as an alternative or addition to a Tanzania-based Serengeti trip. It's roughly on the same latitude band as other Indian Ocean island destinations like the Seychelles and the Comoros, though considerably closer to the African mainland than either of those.

Time zone and practical orientation

Zanzibar operates on East Africa Time (EAT), UTC+3, the same time zone as mainland Tanzania, Kenya, and Uganda, with no daylight saving adjustments during the year. Being close to the equator, day length stays fairly consistent year-round, with sunrise and sunset both landing roughly around 6am and 6pm with only modest seasonal variation — useful to know when planning sunset activities like a dhow cruise, since "sunset" doesn't shift dramatically by season the way it does at higher latitudes.

A brief note on why the geography confuses first-time visitors

Part of the confusion is historical: Zanzibar was its own separate British protectorate and, briefly after independence, its own sovereign state, before uniting with Tanganyika (the mainland) in 1964 to form the United Republic of Tanzania. That history is part of why Zanzibar retains its own government, its own flag, and a distinct cultural identity even though it's constitutionally part of Tanzania today — and why some visitors instinctively think of it as more separate from the mainland than it formally is. Understanding this also explains why Zanzibar has its own visa insurance scheme, its own revenue authority for some taxes, and its own local elections and legislature, even while sharing a national visa, currency, and defence policy with the mainland.

Getting oriented on a map before you go

If you're looking at a map for the first time: find Tanzania on the East African coast, south of Kenya and north of Mozambique. Dar es Salaam, the mainland's largest city, sits roughly midway down that coastline. Zanzibar (Unguja) is the roughly oval-shaped island just offshore from Dar es Salaam. Stone Town sits on the island's west coast, facing back toward the mainland, which is why it's the natural arrival point — flights and ferries from the mainland land closest to Stone Town before you then travel onward to whichever beach area you're staying in.

Quick answers

Is Zanzibar a separate country from Tanzania?

No — it's a semi-autonomous part of the United Republic of Tanzania, with its own local government but shared national functions like defence and foreign affairs.

Is Zanzibar close to the Serengeti?

Not directly adjacent — it's reached from Zanzibar by a flight of a few hours, typically via Arusha, to reach the safari circuit inland.

What's the difference between Zanzibar and Unguja?

Unguja is the main island, usually what people mean by "Zanzibar" in everyday travel talk. Zanzibar technically refers to the whole archipelago, including the separate island of Pemba.

What time zone is Zanzibar in?

East Africa Time, UTC+3, year-round with no daylight saving changes.
