A family vacation on the island of Ibo, Ilha do Ibo in Portuguese, is as much about the history of ivory and slave trade as it is about coral reefs and the rare dugong. Once the second most important town and northern most trading post in Portuguese Mozambique, this small, forested island has been all but forgotten by time. Take a stroll down the island's colonial streets. Tour a 16th century pentagonal fort and intriguing colonial graveyard. Observe craftsman shape filigree bracelets and pendants using age-old Arab techniques. And in contrast to Mozambique Island, here, one can also access the sea. Partake in a snorkeling or scuba diving trip and watch turtles as well as a myriad of colorful fish. Take a whale watching tour and spot dolphin, whale and, if you are lucky, even the rare dugong. And at high tide, watch the harbor as it comes alive with fisherman preparing to set sail.
