We pick-up our travelers at any general area's in Zanzibar island that our guests will provide, then we take them for a ride or walk to Stone town local habour, we then hop on a local motorboat and cruise on sea to Prison Island, also known as Changuu Island or Quarantine Island, is one of the must-see islands in Zanzibar. This island is famous for being planned to be a prison for slaves and coral mine and therefore become to be a station island where were kept people affected by the Yellow fever. After some years, as no longer needed as a quarantine place, Prison Island became a sanctuary for Aldabra Tortoises, one of the largest and longest-lived in the World.
