Backpacking is essentially any foot propelled trip involving an overnight stay. One must carry food, water, and all required gear to their sleeping spot, using a large backpack. Often times, a tent is carried and set up at a backcountry campground, but sometimes there is no designated campground, which means that you are random camping. In rare cases, backpacking may involve staying at a hut where a tent is not required. Backpacking can include any kind of travel such as snowshoeing, skiing, and scrambling, but is more commonly done as a hike.
