Backpacking is an outdoor activity which is popular all over the world. To carry a pack which contains hiking gears means to involve hiking at least one night to a camping location. A great number of backpackers prefer mountainous regions for hiking and many countries possess well-established trails for this kind of activity, for e.x. the Pacific Crest Trail.
Travelers always used packs in their journeys. Overnight camping was spread widely during the First World War when backpacking wasn’t so expensive. Nowadays backpacking is a popular way to explore nature. In 1920s many hikers started to overcome the great Appalachian Trail (2, 000 miles) in the Eastern part of the United States. Many hikers spend all their holidays and even the whole summer with the only wish to overcome the whole length of the trail.
