Hiking
From Wikitravel
Hiking is an outdoor activity which consists of walking in natural environments, often on hiking trails. Hiking may be broadly grouped into two categories.
Wilderness backpacking involves a multi-day hiking expedition where participants carry the required supplies for 2 or more days of survival in the wilderness, and camp en route.
Day hiking involves distances of less than a mile up to longer distances that can be covered in a single day.
