For pure climbing difficulty the established Alpine grading system using the following symbols has been adopted: F = easy; PD = not very difficult; AD = quite difficult; D = difficult; TD = very difficult; and ED = extremely difficult. This can be distinguished further by adding a + or – sign to the grade, giving PD+, AD-, etc. This grading system takes into account both the technical difficulty and overall seriousness of a climb and will be familiar to users of mountaineering guidebooks.

Thus a ski tour may be given a grade of: BSA. With the option of an AD+ ascent and involve sections of S3 steepness. Combined, these gradings hopefully provide the skier with a lot of useful information about the difficulty and demands of the route prior to setting out on tour.
