Mustang is a barren landscape boasting a remarkable spiritual heritage. The 80km-long kingdom borders Tibet on the Central Asian plateau between the Nepalese provinces of Dolpo and Manang. It is also known as ‘Tibet outside the Tibetan border’ as many centuries ago it was part of Tibet, but was annexed by Nepal in the 18th century and survived Chinese invasion in the 1950s. In 1992, the region was re-opened to strictly limited numbers of travellers. Exploring Mustang is definitely an off-the-beaten-track experience so rare to find these days.
