A guidebook presenting 90 routes visiting 109 of Scotland's Corbetts (mountains between 2500 and 2999ft). Covering the area north of the Great Glen, including the Hebrides, the walks require good fitness and navigation skills plus experience in remote mountainous terrain: while many are straightforward ascents, some involve scrambling and river crossings.

The routes range from 7 to 41km (4–25 miles) and include hikes around Knoydart, Glen Affric, Torridon, Strathcarron and the Isle of Skye.
