Prison Island (Giant Tortoises)

This historic island, originally built as a prison fortress in the 19th century, now shelters a sanctuary of ancient Aldabran giant tortoises that roam freely across its lush grounds. You'll wander through crumbling stone structures and peaceful gardens while encountering these gentle giants up close, some weighing over 300 kilograms and living peacefully in their protected habitat. The island offers panoramic views of Zanzibar's coastline and serves as a living museum of both human and natural history.
