Great Mountain Days in Scotland from Cicerone offers 50 of the very best biggies, cherry picked from across the country to reflect the true diversity of the Scottish uplands - the lonely moors of Sutherland; Arran's jagged ridges; the snowy Cairngorm plateaus and the land-sea jigsaw of the west, where bare rocky mountains rise straight from the clear sea. All the must-do peaks and ranges make the cut, but so too do unsung gems where paths are thinner on the ground. There are thrilling scrambles and remote bothy nights, and some optional approaches by bike or kayak.

Some of the 50 walks described here are well known classic challenges – the Lochaber Traverse for instance, or the Cluanie Ridge – while others approach popular hills from novel angles, or weave whole ranges into peak-bagging epics at the upper limit of the feasible (anyone up for the skyline circuit of Glen Coe?). The routes can either be crammed into a single long day or backpacked over two; the pace is up to you. These leg-busters should appeal to everyone from superfit fell runners to wild camping weekenders, fair weather summer walkers to seasoned winter mountaineers. But none are a walk in the park.

This is the third title in Cicerone's Great Mountain Days series, which also includes Snowdonia and the Lake District.
