The scrambler can access most of the individual peaks by their easiest routes. Only the Inaccessible Pinnacle is a graded rock climb (Moderate) by its simplest line but several of the other summits require scrambling skills. Navigation on the ridge is difficult due to jagged terrain and magnetic abnormalities that make compass reading unreliable. The majority of scramblers heading on to the Black Cuillin do so via routes from Glenbrittle (where there is a campsite and a youth hostel) or Sligachan for the northern peaks: due to the remoteness of Loch Coruisk, which can only be reached by boat or a "c." 10 km walk from Elgol, routes starting from this side are less frequented.
