Both have a real place depending on what you are doing and how much time you have, and there is a useful middle option too.

Dala dalas are the local minibuses that run set routes across the island, connecting Stone Town with beach areas and villages. They are extremely cheap, a fraction of a taxi fare for the same distance, and riding one is a genuine, immersive way to experience daily life on the island. The trade-off is real: they can be crowded, run on their own loose schedule rather than a fixed timetable, and are not always the fastest or most comfortable option, particularly with luggage. They suit travellers with time to spare and an interest in the experience itself, more than anyone on a tight schedule.

Taxis are the straightforward option for point to point transport, particularly airport transfers and longer journeys such as Stone Town to the east or north coast. Fares are not metered, so agree the price before you get in, and expect to negotiate a bit, especially if hailing one independently rather than booking through your accommodation. Hotels and resorts can usually arrange a trusted driver, which is worth it for the peace of mind on longer transfers.

The middle option worth knowing is hiring a private driver for a full day, which costs more than a single taxi trip but far less than you might expect, and makes sense if you want to see several spots, such as spice farm tours, Jozani Forest and a beach stop, all in one day without negotiating separate fares each time.

For a first visit, we would suggest taxis or a private driver for your main transfers and any time-sensitive trips, with a dala dala ride as a fun, low-stakes experience if you have a free afternoon and want a taste of local life.
