Backpacking is a form of low-cost, independent international travel. It includes the use of a backpack or other luggage that is easily carried for long distances or long periods of time; the use of public transport; inexpensive lodging such as youth hostels; a longer duration to the trip when compared with conventional vacations; and an interest in meeting the locals as well as seeing the sights. It is typically associated with young adults, who generally have fewer obligations and thus more time to travel. They also have less money to spend on hotels or private vehicles.
