Nepal’s most mountains, hilly and ‘Terai’ (flat) regions offer some of the most spectacular trekking in the world. Treks vary from high altitude routes to simple ones within the Kathmandu Valley. A trekking trip can be of any length you choose, lasting from a week to months. However, the hill country is also often breathtakingly beautiful with pretty villages, attractive houses and revering temples, as well as subtropical lowlands, vast meadows or forests, fast flowing rivers, deep canyons and the cold and barren regions at the feet of the mountain peaks.
