This circuit is considered one of the best treks in the world, this trek takes you through distinct regional scenery of rivers, flora, fauna and above all - mountains.
There are four regions that are passed through on the trek; Lamjung, Manang, Mustang and Myagdi. Lamjung and Myagdi of the lower elevations are both predominantly Hindu and with lush green subtropical valleys with villages and terraced farming.
Manang and Mustang are of the higher elevations and are predominantly Tibetan Buddhist. The Manang people are Gurung (not Tibetan descent) and are very proud of their unique cultural heritage and merging of lower land Gurung and Tibetan cultural influences. People of Mustang identify themselves a lot closer with Tibet and the Mustang region has actually been part of Tibet in history. Mustang also is one of the last places in the world to view the ancient Bonpo Religion in action. Villages to note for Bonpo are Thini and Lupra near Jomsom, and Nargon near Kobang.
