Since for each hiking difficulty a pedestrian tourist adds different points to the description of the route, and the more such points are scored, the more the route is appreciated among professionals.
All of the above applies to professional tourists who have chosen hiking not only as a form of recreation, but also as a sports career, since hiking is a sport. The hiking trails are categorized. They are divided by difficulty from 1 to 6, each category corresponds to a certain number of points and the length of the path.
