The Sundarbans, the world’s largest mangrove forest, is a breathtaking natural wonder spread across India and Bangladesh. Known for its rich biodiversity and unique ecosystem, this UNESCO World Heritage Site is home to the iconic Royal Bengal Tiger, countless bird species, and an extraordinary variety of mangrove plants.
What makes this forest truly unique is its vegetation—plants that have adapted to survive in saline water, tidal flooding, and oxygen-poor soil.
