throughout the world enjoy hiking to wilderness campsites, usually on
established trails. This activity is called backpacking because it involves

beautiful views of the surrounding wilderness, and wildlife seen along the

activities by overseeing park systems, wilderness areas, and protected land.

the National Parks Service, require that backpackers register and obtain permits
(called backcountry reservations) before entering wilderness areas. Others

drinking water. Questions: Backpacking is most suitable for those healthy people because ______.
