The range forms the western section of the Hindu Kush Himalayan Region (HKH) and is the westernmost extension of the Pamir Mountains, the Karakoram and the Himalayas. It divides the valley of the Amu Darya (the ancient Oxus) to the north from the Indus River valley to the south. The range has numerous high snow-capped peaks, with the highest point being Tirich Mir or Terichmir at in the Chitral District of Khyber Pakhtunkhwa, Pakistan. To the north, near its northeastern end, the Hindu Kush buttresses the Pamir Mountains near the point where the borders of China, Pakistan and Afghanistan meet, after which it runs southwest through Pakistan and into Afghanistan near their border. The eastern end of the Hindu Kush in the north merges with the Karakoram Range. Towards its southern end, it connects with the Spin Ghar Range near the Kabul River.
