Trekking in Nepal will take you through a country that has captured the imagination of mountaineers and explorers for more than 100 years. You will meet people in remote mountain villages whose lifestyle has not changed in generations. Most people trust foreigners. Nepal is one of only a handful of countries that has never been ruled by a foreign power. Many of the values associated with a hiking trip at home do not have the same importance during a trek in Nepal. Isolation is traditionally a crucial element of any wilderness experience but in Nepal it is impossible to get completely away from people, except for short times or at extremely high elevations. Environmental concerns must include the effects of conservation measures on rural people and the economic effects of tourism on indigenous populations. Even traditional national park management must be adapted because there are significant population centres within Sagarmatha (Mt Everest) and Langtang national parks.
Trekking does not mean mountain climbing. While the ascent of a Himalayan peak may be an attraction for some, you need not have such a goal to enjoy a trek. As far as most people are concerned, trekking always refers to walking on trails.
