Trekking involves walking along trails that wind through mountains. It requires more time and effort than other forms of travel, but provides greater rewards such as experiencing the spectacular beauty and unique culture of remote regions in Nepal that cannot be accessed by road. Organized camping treks provide the comforts of having porters carry gear, Sherpas set up camp and cook meals so trekkers can enjoy the experience with only a day pack. Trekking companies can arrange different levels of support for comfortable camping treks.
