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.
A trek is physically demanding because of its length and the changes in elevation. On most treks, the daily gain is less than 800 meters in about 15 km, though ascents of as much as 1,200 meters are possible on some days. You can always take plenty of time during the day to cover this distance, so the physical exertion, though quite strenuous at times, is not sustained. You also can stop frequently and take plenty of time for rest.
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.
While trekking you will see the great diversity of Nepal. Villages embrace many ethnic groups and cultures. From the start, the towering peaks of the Himalaya provide one of the highlights of a trek.
During a trek, the Himalaya disappear behind Nepal's continual hills, but dominates the northern skyline at each pass. Annapurna, Manaslu, Langtang, Gauri Shankar and Everest will become familiar names. Finally, after weeks of walking, you will arrive at the foot of the mountains themselves, astonishing heights dwarfed by their surroundings.
