Backpacking (also tramping or trekking or bushwalking in some countries) combines hiking and camping in a single trip. A backpacker hikes into the backcountry to spend one or more nights there, and carries supplies and equipment to satisfy sleeping and eating needs.
Backpacking is a term used to denote a form of low-cost independent international travel, differentiating it from other forms of tourism notably by the following typical attributes: minimal budget use, longer duration traveling, use of public transport and multipliable destinations/countries. The origin of the name comes from the backpacks that budget travelers generally carry in the interests of mobility and flexibility.
