The morning light off Stone Town turns the Indian Ocean into a rim of glass as the boat slips away from shore. Salt air and boat hum put a soft rhythm underfoot; the engine eases and the sea dares you to look farther — toward Prison Island’s weathered ruins and then the white crescent of Nakupenda sandbank.

Conservation
Coral reefs around the sandbank are fragile — avoid standing on corals, use reef-safe sunscreen, and support operators who minimize single-use plastics and respect wildlife.
