Many people enjoy walk as a recreation in the mainly urban modern world, and it is one of the best forms of exercise. For some walking is a way to enjoy nature and the outdoors and for others the physical, sporting and endurance aspect is more important. There are a variety of different kinds of walking, including bushwalking, racewalking, hillwalking, volksmarching, Nordic walking, trekking, and hiking.
Some people prefer to walk indoors on a treadmill, or in a gym, and fitness walkers and others may use a pedometer to count the number of their steps.
In terms of tourism the possibilities range from guided walking tours in cities, to organized trekking holidays in the Himalayas. In the UK the term walking tour also refers to a multi-day walk or hike undertaken by a group or individual. A system of well organized trails exist in many other European counties, as well Canada, USA, New Zealand, and Nepal
