Technique
Winter Munro
Definition
A Winter Munro is a Munro climbed in winter conditions — snow on the ground, ice on rocks, and the technical demand for ice axe, crampons and avalanche awareness. Scottish winter conditions typically run November to April, with the peak season December-March. Winter ascents account for the highest-risk Scottish walking outings.
Etymology & origin
The term 'winter Munro' became common usage from the 1980s as winter hillwalking shifted from a specialist mountaineering pursuit to a mainstream activity within Scottish hill culture. The earlier generation of Scottish hill walkers treated winter conditions as a separate discipline requiring its own kit and training; modern usage treats it as a recognised subset of regular hillwalking.
Context & usage
Winter conditions in the Scottish hills are real winter mountaineering, not just colder hillwalking. The standard summer route to a Munro frequently becomes a different proposition with snow cover: steeper, more committing, with consequences for slipping that are graver than the summer equivalent. The kit list is meaningfully different (see /kit/winter-munro): B2 boots minimum, 12-point crampons (C2 rating to match B2 boots), walking ice axe with self-arrest ability, and full mountaineering clothing including gaiters and goggles.
Skills required: self-arrest with the ice axe, crampon technique on varying snow surfaces, navigation in whiteout (the Scottish winter plateau in cloud is among the most navigation-demanding ground in British walking), avalanche assessment via the SAIS forecast, and the judgement to turn back. Glenmore Lodge runs the standard 2-day winter skills course; the BMC and other providers run similar courses.
Winter Munros are the highest-risk season for Scottish walking fatalities. Most accidents involve walkers without winter-appropriate kit or skills, not experienced winter walkers in bad conditions. The shorter, less-committing winter Munros (Ben Lomond, Schiehallion, the Drumochter Meall summits, Cairn Gorm from the ski centre) are the right learning ground. Glen Coe, the Cuillin, the An Teallach traverse, the Aonach Eagach are not.
The SAIS daily forecast is mandatory reading for any winter Munro day — the avalanche hazard level, named hazardous slope aspects, and snowpack stability are all critical inputs to route choice.

Munro
A Munro is a Scottish mountain over 3,000ft (914.4m) in height with sufficient prominence to be considered a separate hill rather than a subsidiary summit. The current list contains 282 Munros, ranging from Ben Nevis (1,345m) to Beinn Teallach (915m). The list is maintained by the Scottish Mountaineering Club.
SAIS
The Scottish Avalanche Information Service issues daily avalanche forecasts for six Scottish mountain regions during the winter season (typically mid-December to mid-April). Each daily forecast covers avalanche hazard level (low / moderate / considerable / high / very high), unstable slope aspects, snowpack stability and weather influences.
MWIS
The Mountain Weather Information Service is the standard daily mountain weather forecast for Great Britain. MWIS produces region-specific forecasts focused on what matters to walkers: wind speed at altitude, cloud base, freezing level, visibility and precipitation type. Forecasts are issued by 4pm for the next 48 hours.
