Hiking - Encyclopædia Britannica definition
Walking as a recreational activity and sport. Especially among those with sedentary occupations, hiking is a natural exercise that promotes physical fitness, is economical and convenient, and requires no special equipment. Because the hiker can walk as far as he wants, there is no physical strain unless he walks among hills or mountains.
