A dhows’ wake parts the blue as the dhow slips past coral outcrops and into open water; within an hour the city hum fades and the ocean begins to set the day’s tempo. On this full-day excursion from Stone Town, travelers trade the narrow alleys and carved doors for two very different island experiences: the powder-white solitude of Nakupenda Sandbank and the shaded, history-steeped shores of Prison Island (Changuu).

On this full-day excursion from Stone Town, travelers trade the narrow alleys and carved doors for two very different island experiences: the powder-white solitude of Nakupenda Sandbank and the shaded, history-steeped shores of Prison Island (Changuu).
Prison Island’s stone buildings date to the 19th century and carry echoes of Omani trade and colonial-era quarantine practices; today the island is better known for its Aldabra and Seychelles giant tortoises and the fringing coral reefs. Nakupenda is a depositional sandbar formed by currents of Menai Bay, a shifting platform of white sand and shallow turquoise that invites long swims and snorkeling in shallow seagrass beds.
Expect a mix of calm swims, guided snorkel stops over coral bommies, and a seafood lunch served on the sandbank. Guides typically explain local marine life and the islands’ role in Zanzibar’s fishing communities; conversation often turns practical—tides, sun, and the reef’s health.
Practical notes: boats depart from Stone Town harbors in the morning; bring reef-safe sunscreen, a hat, and water shoes for rocky shallows. Snorkeling gear is commonly provided, but if you’re picky about fit bring your own mask. Because weather and tides shape the sandbank, operators may adjust timing; pick a morning departure in the dry season for the clearest water and calmest seas.
