Steeped in undisturbed Tibetan Buddhist traditions, Upper Mustang is a hidden gem in north-west Nepal, known for its ancient monasteries, traditional villages, cliffside cave dwellings, and the walled capital of Lo Manthang. This trek leads through a striking semi-arid desert of vibrant rock formations, deep ravines, and snow-capped peaks, with views of the majestic Kali Gandaki Gorge and serene yak grazing pastures. Commonly referred to as "Little Tibet," Mustang has a complex history dating back to the 8th century and is shrouded in legends, myths, and records of visits by historical figures such as the Tibetan poet Milarepa.
