Sky Caves of Mustang & Loba Trail
The Sky Caves of Mustang & Loba Trail Trek (12 Days) is a fascinating archaeological and cultural expedition exploring one of humanity’s greatest cliffside mysteries. Carved high into the vertical, fluted sandstone canyon walls of Upper Mustang are more than 10,000 ancient man-made caves dating between 1000 BC and 1400 AD.
Discovered to have served three distinct historical epochs—first as burial chambers, later as fortified cliff dwellings during periods of regional warfare, and finally as Buddhist meditation sanctuaries—these sky caves contain priceless manuscripts, murals, and intact wooden ladders. Climb inside the multi-story Jhong Sky Cave complex in Chhoser (3,900m), visit the rock-embedded monastery of Nyphu Gompa, wander the 15th-century fortified capital of Lo Manthang (3,840m), and explore Ghar Gompa and the blood-red cliffs of Dhakmar.
