Chilas Airport (CHB)

Chilas Airport (CHB), also known by its ICAO code OPCL, is a remote and historically significant mountain airfield located in the town of Chilas, within the Gilgit-Baltistan region of northern Pakistan. Situated at an elevation of approximately 4,146 feet in the heart of the Himalayas, the airport acts as a critical aviation node for the Diamer District. The airfield is positioned on a rugged plateau overlooking the Indus River and provides a vital link for government logistics, emergency services, and the region's developing infrastructure projects.

The airport has a long heritage, having been originally constructed by the British Raj in 1927 as a strategic outpost. Today, the infrastructure consists of a single 1,372-meter (4,500-foot) paved runway that is surrounded by the towering peaks of the Karakoram Range. There is no traditional passenger terminal building with modern commercial amenities; instead, the facility features basic administrative offices and a sheltered area for waiting passengers and crew. Due to its challenging mountain location and lack of advanced navigational aids, the airfield operates strictly under Visual Flight Rules (VFR) during daylight hours, with flight schedules heavily influenced by the volatile mountain weather.

Currently, Chilas Airport is primarily used for military transport, government flights, and essential logistics supporting the construction of the massive Diamer-Bhasha Dam. While it does not host regular scheduled commercial passenger services, the airfield is a vital hub for private charters and high-altitude mountain expeditions, acting as a secondary gateway for climbers heading toward Nanga Parbat, the world's ninth-highest peak. Ground transportation from the airstrip into central Chilas is typically arranged via private 4WD vehicles or government shuttles. Its presence is fundamental to the regional economy, ensuring that this remote part of the Karakoram Highway remains connected to major provincial hubs like Gilgit and the national capital, Islamabad.
