Things To Do

    Bendera Bay at St John’s Island – A showcase of community stewardship in conservation

    The 3.9-hectare Bendera Bay is nestled within St John’s Island, and comprises a lagoon with a variety of mangrove, coral, seagrass, sandy shore and rocky shore habitats. This variety of habitats thus provides unique opportunities for outreach and research.

    Currently, the area is not open for public access as it is closed for conservation and research. Activities for the public will be organised from 2021 onwards.
