The day begins with a motorized boat easing away from Stone Town’s reef rim; the Indian Ocean opens like a low, cool breath and the skyline of minarets shrinks behind you. Salt spray and the cry of gulls set the pace as you head first for Prison Island, where white sand and a small forest give way to slow-moving Aldabra tortoises that have lived under a peculiar human history.
