Many islands promote their destinations by including islets that surround them. Conscious of the competitive tourism market, the move is based on the need for tourism diversification. Islets are endowed with unique flora and fauna, and when included in the tourism package, islets receive considerable prominence in the gaze of tourists looking for authentic experiences. Mauritius Island has not lagged behind in adopting this trend. Studies show that islets surrounding Mauritius are major tourism assets, but these seem to have received insufficient attention in tourism studies. The current study uses Jordan's core-periphery model to investigate Ilot Bernaches, one of the popular islets of Mauritius. The uniqueness of this study is two-fold: first, it seeks to investigate implications of tourism development at Ilot Bernaches, and second, it makes a case for setting up an islet management authority. The research design is based on a mixed methodology. The major findings reveal that Ilot Bernaches has potential to diversify the existing tourism product and adds value to the Mauritian tourism product. The study discusses destination management implications, makes recommendations regarding tourism development at Ilot Bernaches, and sets the groundwork for further studies of islets in tourism. It is recommended that an islet management authority be established to help cope with core-periphery tensions.
