The factors that traditionally differentiate backpacking from other forms of tourism include but are not limited to the following: use of public transport as a means of travel, preference of youth hostels to traditional hotels, length of the trip vs. conventional vacations, use of a backpack, an interest in meeting the locals as well as seeing the sights.
