Prison Island Zanzibar: History, Giant Tortoises & Snorkeling
Just a short boat ride from Stone Town lies Changuu Island, more famously known as Prison Island. This intriguing destination offers a captivating blend of history, a unique wildlife encounter with giant Aldabra tortoises, and opportunities for refreshing snorkeling in its crystal-clear waters.
A Glimpse into Prison Island's Past
Originally uninhabited, the island was purchased by the British First Minister of Zanzibar, Lloyd Mathews, in 1893. His intention was to build a prison for rebellious slaves, hence its enduring moniker, "Prison Island." However, the prison facility was never actually used for its intended purpose.
Instead, at the turn of the 20th century, the island found a different, more humanitarian role. It was transformed into a quarantine station for patients suffering from yellow fever and other contagious diseases. Ships arriving from affected regions would offload passengers here, who would then undergo a period of observation before being allowed onto the main island of Zanzibar. Remnants of these old quarantine buildings can still be seen today, offering a tangible connection to this chapter of the island's history.
The island's original name, Changuu, is derived from the Swahili name for a species of fish prevalent in the surrounding waters. While its history is somewhat somber, today it stands as a testament to adaptation and transformation, evolving into a popular tourist attraction.
Encountering the Ancient Giant Tortoises
One of the primary draws of Prison Island is its resident population of Aldabra giant tortoises (Aldabrachelys gigantea). These magnificent creatures are not native to Zanzibar but were brought to the island from the Seychelles in the late 19th century as a gift from the British governor. What started with just four tortoises has grown into a thriving sanctuary, with many individuals now over a century old.
Walking among these gentle giants is a truly unique experience. Visitors are often given the opportunity to feed them, typically with leafy greens, and observe them up close. The sanctuary plays a vital role in their conservation, providing a safe environment for breeding and protecting them from poaching. Many of the tortoises are marked with numbers on their shells, indicating their age, with some reaching impressive ages of over 150 years.
It's important for visitors to approach these ancient animals with respect and gentleness. Follow the guidelines provided by your guide to ensure a safe and enjoyable interaction for both you and the tortoises.
Did you know?The Aldabra giant tortoise is one of the largest tortoise species in the world, with some individuals weighing over 200 kilograms (440 pounds). Their longevity is remarkable, making them living relics of a bygone era.
Snorkeling and Beach Relaxation
Beyond its history and tortoises, Prison Island offers a refreshing escape to pristine waters and soft sandy beaches. The island is surrounded by vibrant coral reefs, making it an excellent spot for snorkeling. Equipped with a mask and snorkel, you can explore an underwater world teeming with colorful fish, intricate coral formations, and other fascinating marine life.
The clear, warm waters provide excellent visibility, whether you're a seasoned snorkeler or trying it for the first time. Many tours include snorkeling gear, but you can also bring your own if you prefer. While not as expansive as the reefs around Mnemba Atoll, the snorkeling here still offers a delightful glimpse into Zanzibar's rich aquatic biodiversity.
After your historical exploration and underwater adventure, the island's idyllic white sand beach invites you to relax. Unwind under the sun, take a leisurely stroll along the shore, or simply enjoy the tranquility and panoramic views of Stone Town in the distance.
