Explore Prison Island (Changuu Island), a small island just 1 km long and 230 meters wide, rich with fascinating history. Originally owned by an Arab slave trader to prevent escapes, it later housed a quarantine station and a prison building—now a guesthouse. Though it never actually held prisoners, the island became a sanctuary for giant tortoises brought from Seychelles in 1820, some over 150 years old.

Visitors can meet these friendly tortoises up close, admire stunning peacocks, snorkel among vibrant marine life, and enjoy the sun-drenched shores. The trip finishes at the beautiful Nakupenda Sandbank Beach, perfect for relaxing and soaking up the tropical vibes.
