What is the definition of 'backpacking' in the context of travel?

Backpacking is defined as a form of low-cost, independent travel where individuals typically carry their belongings in a backpack. This style of travel emphasizes exploring destinations at a more personal and unrestricted pace, often with a focus on experiencing local cultures and environments. Backpackers generally seek budget accommodations, use public transport, and may engage in various activities such as hiking, camping, or staying in hostels. The essence of backpacking lies in its flexibility and the opportunity for spontaneous adventure, allowing travelers to immerse themselves in their surroundings rather than adhering to a strict itinerary.

The other options describe different travel styles. Organized group travel involves pre-planned itineraries and activities, which contrasts with the spontaneity of backpacking. Luxurious travel experiences usually focus on comfort and premium services, which is not a characteristic of budget-conscious backpacking. Finally, while public transportation can be a part of backpacking, it is not exclusive to this travel style, as backpackers may also choose to walk or bike, making that option too narrow to define backpacking fully.
