It was built during the Han dynasty as part of the Han Great Wall. The beacon was reused and renovated during the Tang dynasty. During the Sui and Tang dynasties, the pass was the main trade route linking Tarim Basin and Western Turks in Central Asia.

The name Xuanzang used for the passage was "", it was said to be northwest of "Kingdom of Baluka", modern day city of Aksu. However, others argue that was Muzart Pass.
The pass was surveyed in 1881 by both Chinese and Russian counterparts as part of "Protocol of Chuguchak of 1864" demarcating the border in the region between the Russian Empire and the Qing Dynasty. During the Urkun incident of 1916, over 100,000 Kyrgyz reportedly died fleeing from Tsarist forces they attempted to reach China through the Bedel Pass. 
The pass is currently closed to traffic. Kumtor Gold Mine is located down the road on the Kyrgyz side. Along the path on the Chinese side is also the ruins of a KMT era sentry post which is a local cultural heritage site.
