The western region of Nepal covers two zones: Mahakali and Seti covering 9 districts. Western region Nepal has a large population with majority of people Hindus and Buddhists.
Khaptad National Park, Sukla Phanta Wildlife Reserve and Royal Bardiya National Park are the most major attractions of this region. The trekkers can experience the view of Api Himal, Se Phoksundo Lake and Rara lake. The trekkers can experience the view of Api Himal, Se Phoksudo Pond, Rara Pond, Malakali River and Seti River.
(Raute is nomadic indigenous ethnic group that exist in small settlements in the regions of western Nepal. Their population is estimated to be only about 650 people.)
This region is remote because of its relative inaccessibility and lengthy distance from Kathmandu. As it falls in the rain shadow of Dhaulagiri Himal, this region receives very little rainfall causing poor vegetation. Another reason that discourages trekkers in western Nepal is that many of the culturally and scenically exotic regions are in restricted areas with high permit fees. Many of the trails in the west continue to the northern side of the Himalayan ranges of Nampa, Saipal and Kanjiroba, making it easy for trekkers to zip up trails along river valleys and into Tibet - a practice that both the Nepalese and Chinese would like to dispirit. Some of these treks, including Shey Gompa to the north of Phoksumdo Lake and Humla to the north-west of Jumla are portrayed in the sector on Restricted Areas.
The history and anthropology of western Nepal is complex but fascinating. It has very less population, though they have the significant influence on the area through trading. In many villages the houses are built closely together one atop another, climbing up the hillside and sharing common roofs with the few stairs inside the dwellings. Tibetan-style houses can be found here where people climb from one level to another on carved log ladders situated outside the house.
Cultural root of this region extends from north to Tibet, where as in west it extends to Kumaon in India. The Chhetris of western Nepal are categorized into three groups: Thakuris, who are the aristocracy; normal Chhetris as found throughout Nepal; and Matwali Chhetris, "those who drink liquor". The status of Matwali Chhetris is enthralling because many Tibetan immigrants long ago masqueraded as Chhetris. For many generations they have evolved their own form of religion that is a peculiar mixture of Hinduism and Buddhism. The trekking season is from late spring and throughout the summer until late October.
