The Northern Highlands Central area is defined by the SMC guidebook of the same name. With the exception of the inclusion of the Ben Wyvis range, the northern limit is the A835 Inverness to Ullapool road. The southern limit in the west is based on the A832 Kinlochewe to Achnasheen road, but the crags reached from the Loch Maree to Gairloch road are also included. The most southerly part of this area includes Srathconnon, Strathfarrar, Glen Cannich and Glen Affric. This area includes a wealth of high quality trad climbing, varying from the remote mountain crags of the Fisherfield area to the very accessible Gairloch, Stone Valley and Tollaidh crags, and also the sea-cliffs of Rubha Mor. The climbing on the western crags is mostly on gneiss, but further east there are good mountain and outcrop schist crags, of which the most popular are Glenmarksie Crag, Meig Crag and Creag Ghlas.
