Babusar Pass or Babusar Top () (elevation ) is a mountain pass in Pakistan at the north of the 150 km (93 miles) long Kaghan Valley, connecting it via the Thak Nala with Chilas on the Karakoram Highway (KKH). It is the highest point in the Babusar Valley that can be easily accessed by cars. The Babusar Pass connects Khyber Pakhtunkhwa with Gilgit Baltistan. It is one of the most dangerous routes in Gilgit-Baltistan. Every year many deaths happen here due to the mountainous slopes, which are among the most dangerous in the world. The most common reason for death is the brake failure of cars due to inexperience. Babusar Top was originally known as Babur Top, originating from the fact that the Mughal emperor Babur used to pass through this area in the early 16th century. Nowadays however, it is commonly referred to as Babusar Top.
