Rangamati Lake : Rangamati is a verdant rural area belonging to the Chakma tribe, is open to visitors, as is Kaptai Lake. The lake, ringed by thick tropical and semi-evergreen forests, looks like nothing else in Bangladesh. While the lake itself is beautiful, the thatched fishing villages located on the lakeshore are what make a visit really special.Boats that visit the villages leave from Rangamati. Bring your swimming gear because you can take a plunge anywhere.
