The Corbetts (Scotland's 2500-2999ft mountains) are every bit as interesting as the Munros (3000ft and over), often clear when the Munros are in cloud, walkable on short winter days, free of the peak-bagging crowds of their taller neighbours. Volume 1 of this two-volume Cicerone guide covers the Corbetts to the south of the Great Glen, which runs from Fort William to Inverness enclosing Loch Ness, probably Scotland's best-known loch. Choosing the best, rather than the quickest, routes up each summit the author covers 112 peaks in 95 routes, divided into 11 areas, each of which could be covered in a fortnight's holiday. South of Glasgow and Edinburgh are the moorland hills of the Southern Uplands, where seven peaks rise to Corbett status. In the Southern Highlands plenty of interesting Corbetts provide spectacular views of the Munros with easy access from Edinburgh and Glasgow. The Corbetts of the Eastern Highlands and the Monadhliath Mountains sit in sprawling heather plateaus, ideal for those seeking solitude. The South-West Highlands are known for their rocky peaks in places like Glen Coe and the highlights of Volume 1 are probably Arran and Jura, with their similarly rocky and isolated summits.
