The Baikka Beel:
Sreemangal and Moulvibazar both have Baikka Beel, a retreat for fish and birds. It is a portion of Hail Haor, and the 1000-hectare beel is made up of coastal areas with evolving vegetation and a rim of native tropical rainforest. Many birds migrate through this area and thousands more live here. Bird-watching is possible all year long. The sound of birds chirping will engulf you as shortly as you enter the pond. At the core of the beel is a watchtower. Birds, lilies, lotuses, and some other underwater plants and flowers can all be seen from the beel. There are 160 species of birds, including migratory ones, and 98 species of fish, most of which are local. According to experts, Baikka Beel is the prime spot in the nation for viewing birds. The best place to spend the night is Sreemangal, which has many hotel guest houses.
