Chittagong Hill Tracks

Decidedly untypical of Bangladesh in topography and culture, the Chittagong Hill Tracts have steep jungle hills, Buddhist tribal peoples and relatively low-density population. The tracts are about 60km (37mi) east of Chittagong. The region comprises a mass of hills, ravines and cliffs covered with dense jungle, bamboo, creepers and shrubs, and have four main valleys formed by the Karnapuli, Feni, Shangu and Matamuhur rivers.
Rangamati, a lush and 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. >more> http://www.bengaliwiki.com/page/Chittagong+Hill+Tracks
