Chittagong Division (officially Chattogram Division) is a region in Bangladesh.
During the Pakistan period Chittagong division included the Sylhet Division then as district of East Pakistan.
Chittagong Hill Tracts - 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 has four main valleys formed by the Karnapuli, Feni, Shangu and Matamuhur rivers. The hills rise steeply thus looking far more impressive than what their height would imply and extend in long narrow ridges. The highest peaks on the northern side are Thangnang, Langliang and Khantiang while those on the southern side are Ramu, Taung, Keekradang, Tahjindong (4632 ft, highest in Bangladesh), Mowdok Mual, Rang Tlang and Mowdok Tlang. The Hill Tracts is divided into three districts, namely Rangamati, Khagrachari and Bandarban.
Visit the shipbreaking yards on a day trip from Chittagong, a phenomenal (and dangerous) practice.
It is important to be particularly careful in this area as kidnappings have, can and do occur. Also, the violence shown in this particular region is commonplace, and it is usually due to politics. You should be very cautious, and maybe think again if going to the Chittagong Hill Tracts Region is entirely necessary.
