Hiking - Australians use the term bushwalking for both on- and off-trail hiking. New Zealanders use tramping (particularly for overnight and longer trips), walking or bushwalking. Hiking in the mountainous regions of Nepal and India is sometimes called trekking. Overnight hiking is called backpacking in some parts of the world. Hiking a long-distance trail from end to end is referred to as thru-hiking in some places.
