1. Bo Hong peak, so called because it used to be rarely visited by people, therefore soots were born in great numbers on this peak. It is 716m high, toward the West;
2. Head peak, so called perhaps because it might be the first discovered by people when they climbed the mountain via the Thum Chung market. It is 584m high, toward the North;
3. Ba or Phnom Barech peak, so called because, here, there is a Temple of Ba Chua Xu. 579m high, toward the South;
4. Buom (Butterfly) peak, so called because Mr Buom and Mr Voi, Khmer born, the generals of Reverend Co Quan Tran Van Thanh, disciples of Buu Son Ky Huong ̣(Jewel Mountains and Strange Perfume). They retired as hermits here and attained Tao enlightenment here; and
