1. What is Zanzibar Island Tanzania?
Zanzibar is actually not an island but an archipelago, i.e., a group of islands.
Unguja, the biggest island in the archipelago, is often commonly referred to as Zanzibar Island though.

2. Is Zanzibar a Country?
No, Zanzibar is a semiautonomous archipelago in the United Republic of Tanzania.
3. What Currency Is Used on the Island of Zanzibar?
The official currency of Zanzibar is the Tanzanian shilling, though due to the archipelago’s vibrant tourism sector, many major world currencies are accepted in Zanzibar (especially at hotels & for tours).
Such currencies include US dollars, Euros, Pounds, etc., but especially US dollars.
Where Is Zanzibar Located?
Zanzibar Island, often simply called Zanzibar, is a semi-autonomous region of Tanzania located off the eastern coast of Africa in the Indian Ocean. Known for its stunning white sand beaches, turquoise waters, and a rich blend of African, Arab, Indian, and European cultural influences, Zanzibar is both a historical treasure and a modern-day tourist haven. The island’s official name is Unguja, although many people refer to the entire archipelago, including Pemba and several smaller islands, as “Zanzibar.”
One of the most striking features of Zanzibar is its history. For centuries, Zanzibar was a major trading hub in the Indian Ocean, with merchants from Oman, Persia, India, and later Europe docking along its shores. The island became especially significant in the 17th and 18th centuries as a center for the spice trade—particularly cloves—as well as a hub for the East African slave trade.
The legacy of this complex history is visible in the island’s architecture, religion, language, and food.
Stone Town, the historic heart of Zanzibar City and a UNESCO World Heritage Site, is the most vivid representation of this heritage. A labyrinth of narrow alleys, coral stone buildings, intricately carved wooden doors, bustling markets, and ancient mosques, Stone Town feels like a place suspended in time. It was once the seat of the Omani sultans and home to thriving Arab and Swahili communities.
Notable landmarks include the Old Fort, the House of Wonders (Beit-al-Ajaib), and the former slave market site near the Anglican Cathedral. A visit to the Freddie Mercury Museum—dedicated to the Queen frontman who was born in Zanzibar—is also popular among tourists.
Zanzibar’s culture is deeply rooted in Swahili traditions, but it’s also layered with Arab, Indian, and European influences. Swahili, an Afro-Arabic language, is the primary language spoken, although English is widely understood, particularly in tourist areas. The island’s population is predominantly Muslim, and this is reflected in local customs, dress, and daily life. The call to prayer echoes through the streets, women wear colorful kangas or hijabs, and traditional dhow boats still sail the waters around the island.
Tourism is a major part of Zanzibar’s economy today.
The island attracts visitors looking for both cultural immersion and natural beauty. The beaches—such as Nungwi, Kendwa, Paje, and Matemwe—are renowned for their powdery sands and clear, warm waters. These coastal areas offer opportunities for snorkeling, scuba diving, kitesurfing, and dhow cruises.
The coral reefs surrounding the island are rich in marine biodiversity, making it a top diving destination.
The interior of the island is just as intriguing.
The Jozani Forest Reserve, home to the rare red colobus monkey, showcases some of the island’s unique flora and fauna. Spice tours, where visitors can learn about and taste cloves, cinnamon, nutmeg, and vanilla directly from local farms, are a popular activity that ties back to Zanzibar’s reputation as the “Spice Island.”
