Walking routes on this site are graded by their three key elements. They are, strenuousness, navigation and technicality. Each element has a level between 1 to 5, the easiest being 1 and the hardest being 5. The grades are allocated to routes under normal ground and weather conditions. However, as with all mountain activities, ground and weather conditions can deteriorate dramatically and make the routes considerably harder or in some cases impossible.
