Chilas

The boulders along the Indus are covered in marks — ibex, Buddhas, hunting scenes, stupa diagrams — scratched and pecked into dark river-worn rock by hands spanning three thousand years. The Karakoram Highway cuts through the gorge above, but down by the water, the only company is petroglyphs and the sound of the Indus forcing itself through one of the deepest river valleys on Earth.

Chilas sits at the point where the Indus River squeezes through the Karakoram's narrowest gorge in Diamer district, Gilgit-Baltistan. The surrounding rocks bear one of South Asia's densest concentrations of petroglyphs — over 50,000 individual carvings documented across sites including Chilas Bridge, Thalpan, and Shatial. The images span from the Bronze Age through the Gandhara Buddhist period to Islamic-era inscriptions, recording the passage of traders, pilgrims, and armies along the Indus corridor for over three millennia. Many depict Buddhist stupas and devotional figures, evidence that the Karakoram Highway corridor was once a major Buddhist pilgrimage route connecting Gandhara to Central Asia. Chilas serves as a stopping point for travellers between Islamabad and Gilgit, with Nanga Parbat's western flanks visible from points along the road. The petroglyphs are unenclosed and unguarded — visitors walk among them freely, the carvings warm to the touch under the gorge sun.
