Prison Island Adventure Tour

Safari summary

A visit to Prison Island, locally known as Changuu Island, is one of those experiences in Zanzibar that stays with you long after your trip is over. Just a short and peaceful 30-minute boat ride from Stone Town, this small island is a perfect blend of history, nature, and relaxation. It’s not just another island to tick off your list it’s a place that invites you to slow down, breathe, and enjoy the simple pleasures of island life while connecting with Zanzibar’s fascinating past.
The name “Prison Island” might sound a little intimidating, but the island was never truly used as a prison for criminals. In its early days, it was home to rebellious slaves, and later, during the colonial period, the British built structures here to serve as a quarantine station for people with yellow fever and other diseases. Today, the old stone buildings still stand, quietly holding onto their stories. Walking through these ruins, it’s easy to imagine the lives of those who once stayed here their challenges, their hopes, and the history that shaped the island. It’s a calm and educational way to step into the past while enjoying the serene surroundings.
What makes Prison Island truly famous, however, is its giant Aldabra tortoise sanctuary. These gentle giants were gifted to Zanzibar by the Seychelles more than a century ago, and they have thrived here ever since. Some of the tortoises are over a hundred years old, with shells that seem to carry the wisdom of time. As you stroll through the sanctuary, you will see them moving slowly, sometimes coming close with quiet curiosity. Visitors often get the chance to feed them, take photographs, or simply watch them in peaceful wonder. Standing next to a tortoise that may have been alive long before you were born is a unique and almost magical experience that leaves most guests smiling.
The island itself is surrounded by soft white sand and clear turquoise waters, creating a picture-perfect setting. After exploring the history and meeting the tortoises, you can spend time relaxing on the beach. The water is warm and inviting, perfect for a refreshing swim. You might choose to sit under the shade of a tree, feel the gentle sea breeze on your face, or simply lie back and watch the clouds drift across the endless blue sky.
Prison Island also offers a wonderful opportunity for snorkeling. The waters around the island are teeming with life, from brightly colored fish darting between corals to the quiet beauty of the underwater world. Even if you are new to snorkeling, the shallow and clear waters make it easy to explore. With just a mask and snorkel, you can discover an entire hidden world beneath the surface, adding a touch of adventure to your relaxing day.
The journey to and from the island is equally enjoyable. The short boat ride from Stone Town offers scenic views of the coastline, dhows sailing in the distance, and the occasional playful dolphin. The gentle rocking of the boat and the sound of the waves create a peaceful feeling that perfectly sets the tone for your island adventure.
What makes this tour so special is the balance it provides. In just a few hours, you get to explore history, meet incredible wildlife, enjoy the beach, and experience the sea. It’s ideal for couples seeking a romantic outing, families wanting a fun and educational experience, or solo travelers hoping to connect with nature and tranquility.
When you return to Stone Town, you carry more than photographs of tortoises and sparkling waters. You take home a sense of calm, a connection to the island’s history, and the memory of enjoying simple yet profound moments in one of Zanzibar’s most charming corners.
In the end, a trip to Prison Island is not just about visiting a destination it’s about creating memories. Memories of touching a tortoise older than your grandparents, swimming in crystal-clear waters, feeling the sun and breeze on your skin, and experiencing the quiet magic of a small island in the middle of the Indian Ocean.
