Hiking is a physical activity or sport that consists of walking in the open air, generally following paths or trails marked to enjoy nature, landscapes and their elements of historical and cultural interest. It is considered one of the forms of hiking or mountaineering, open to the general public because it does not need a great physical or technical preparation. In hiking, sport and culture come together. The route of the paths avoids as much as can the passage of roads and asphalted roads, as well as the great unevenness that supposes the ascent to peaks and mountains.
