Backpacking is the outdoor recreation practice of carrying gear on one's back while hiking for more than a day. It is often an extended journey and may involve camping outdoors. In North America, tenting is common, whereas simple shelters and mountain huts, widely found in Europe, are rare. In New Zealand, hiking is called tramping, and tents are used alongside a nationwide network of huts. Hill walking is equivalent in Britain, though backpackers make use of a variety of accommodation, in addition to camping. Backpackers use simple huts in South Africa. Trekking and bushwalking are other terms used to describe multi-day backpacking trips, with the term Trekking emphasizing a more self-reliant approach to Backpacking in more remote areas. The terms walking tour or long distance hike are also used.
