Trekking is different from other sorts of travel for a few different reasons. It tends to be less-structured than another sort of travel, as weather conditions and topography help influence travel plans more than plane flights or hotel availability. As travelers move on foot through often-rural areas, trekking gives travelers an up-close view of the incredible scenery. Many trekkers travel through isolated areas, giving them an experience much different than those who travel in organized groups to more-popular destinations. It often allows them to interact with nature, doing anything from climbing a rock wall to navigating across a mountain or entire mountain range.
Trekking can be done anywhere in the world. Several areas are particularly popular with travelers, including the mountainous regions such as the Himalayas in Asia ( Specially Nepal ) and the Andes in South America. However, Treks have been organized in other less-touristed areas regions on almost every continent. Trekking can result in a trip as long or short as participants decide, from trips of a week or more to expeditions that last more than a year. Trekking can be as athletic and adventurous as participants decide. The less-structured nature of trekking and a world of destinations help attract a wide variety of participants to the activity.
Several pieces of gear help make trekking more enjoyable. One is a comfortably-fitting backpack. Many trekkers travel for extended periods and need to carry all of their belongings with them. A sturdy backpack can comfortably fit more than 20-40 pounds (10-20 kilos) of clothing and gear. Another important item is sturdy hiking boots. When covering long distances, wearing the right pair of boots can make the difference between enjoying a trip and being in pain. Other survival equipment, such as warm clothing, a first aid kit and a supply of food and water is also very important.
Trekking is best attempted initially with someone who has experience or in a professionally-led group. This can help introduce those new to trekking to the special skills required to successfully make an overland journey of significant length. A number of outdoor stores and organizations offer classes and plan trips that can help give an idea of the gear and physical ability required in trekking.
