Spend a full day sailing a traditional dhow to Nakupenda Sandbank and Prison Island for clear-water snorkeling, giant tortoises, and a Swahili lunch on the shore. This guided trip blends easy marine exploration with a short historical stop at Changuu.
More ways to explore the area's outdoor wonders
You step off the dhow onto powdery white sand that vanishes with the tide—Nakupenda’s sandbank holds the ocean like a glass bowl and dares you to wade into it. Salt and spice hang in the air as the boat rocks gently and the reef beyond reveals bright parrotfish and slow-moving surgeonfish.

Go early for calm seas
Morning departures usually have gentler currents and better visibility for snorkeling; aim for the first boat when possible.
Use reef-safe sunscreen
Protect coral and your skin—apply reef-safe sunscreen before you board and reapply after swims.
Secure belongings on the dhow
Bring a dry bag or leave valuables in your hotel; boats have limited dry storage and gentle rocking can shift gear.
Bring small change
Cash is useful for tips, extra drinks, or souvenirs in Stone Town—ATMs can be unreliable near the docks.
Reef-safe sunscreen
Protects skin and prevents damage to coral ecosystems in shallow snorkeling zones.

Snorkel mask (personal)
