The Salt Range is a hill system in the Punjab province of Pakistan, deriving its name from its extensive deposits of rock salt. The range extends from the Jhelum River to the Indus, across the northern portion of the Punjab province. The Salt Range contains the great mines of Mayo, Khewra, Warcha and Kalabagh, which yield vast supplies of salt. Coal of a medium quality is also found.

Two interesting sites are close to Kathwai, Kutte Mar and Tulaja fort. At Kuttee Mar to the Northeast of Kathwai are Muslim graves made of Kangar and the purported grave of a dog that is said to have died defending the wedding procession of its owner from an attack by bandits. Kutte Mar may have been the place where the Khura inscription of Toramana was found (Buhler 1891-92, 238-41; Sircar 1965: 422-4). If this assessment is correct, a Buddhist monastery was established here around 500. A.D. This inscription and another fragmentary inscription found at Sakaser (Pakistan Archaeology 5, 1968: 284-70) confirm that this area was a flourishing, centre for Buddhism, which is borne out by the extensive archaeological remains.
