Ḍim Pāhāṛ () is a hill located in Bandarban district, Bangladesh. The hill is located right in the middle of Ali Kadam and Thanchi upazilas. The boundaries of the two upazilas have been determined by this hill. The highest road of Bangladesh has been built through this hill at an altitude of 2,500 feet above sea level. At an altitude of 2,500 feet, the hilltop is shaped like an egg, so the locals call it Dim Pahar, which means "Egg Hill" in Bengali. Description
