About Nijhum Dwip National Park

Nijhum Dwip National Park is a protected island and mangrove park in the Bay of Bengal off southeastern Bangladesh. The park conserves mangrove forest, tidal flats and coastal wildlife.

The island formed naturally in the Meghna estuary and has long supported local fishing and small-scale habitation; it received protected status to conserve its mangrove ecosystems and wildlife. Management focuses on habitat protection and controlled visitation.

The park sits offshore in the Bay of Bengal within Chittagong Division and is accessed by boat from nearby coastal towns on the Bangladesh coast.

  • Ecosystem and wildlife: is a mangrove-covered island park known for birdlife, estuarine habitats and small populations of spotted deer and other wildlife
  • Access: reachable by boat from local coastal towns and used for nature-based visits and birdwatching

Tips for Visiting Nijhum Dwip National Park

  • Plan your visit in the dry season (roughly November-April) when sea crossings are more reliable and wildlife/birdwatching is at its best; avoid the monsoon months when boats and access can be disrupted.
  • Access Nijhum Dwip by boat from the mainland; arrange boat transport in advance through local operators at nearby mainland ports (for example Hatiya/Noakhali area) and confirm departure times with tides and weather.
  • Bring binoculars and aim for early morning or late afternoon for the best wildlife activity-many visitors miss prolonged bird and deer activity at dusk, so staying through sunset rewards wildlife viewing.
