The natural attractions of Bangladesh are intimately tied to the country's environmental health and conservation efforts.
* **Protected Areas:** Bangladesh boasts several national parks and wildlife sanctuaries, most notably the Sundarbans Reserve Forest, Lawachara National Park, and Bhawal National Park. * **Air Quality:** Urban attractions in Dhaka often suffer from poor air quality (high PM2.5 levels), especially during the dry winter months. Natural attractions in Sylhet, Bandarban, and the coastal belt offer significantly cleaner air. * **Water Quality:** River pollution is a concern near major cities, but eco-tourism projects are actively working to preserve the pristine nature of highland rivers like the Sangu and lakes like Kaptai. * **Sustainability:** There is a growing eco-tourism movement. Resorts in the Sylhet tea estates and Saint Martin's Island are increasingly adopting solar energy, rainwater harvesting, and plastic-free policies.
