Cairnsmore of Fleet

Cairnsmore of Fleet (711m) is the granite dome at NX50 that dominates the lower Cree valley and gives the surrounding National Nature Reserve its name. The hill features in John Buchan's "The Thirty-Nine Steps" — Hannay's flight across "the moors of Galloway" took him over these very flanks. From the summit cairn the view stretches over the Wigtown peninsula to the Solway, the Isle of Man and on the clearest days as far as Snowdonia.

Park at Cairnsmore Estate (NX509670) where waymarked access begins. The path climbs gradually through plantation forestry, breaking out onto the open hillside near the Knee of Cairnsmore. From there a well-trodden line rises to the summit dome, often boggy after rain. About 13km return with 583m climbed; an unmistakable route in clear weather.

Terrain

Granite blocks emerge through peat between 500m and the summit; the going on the upper dome is on bilberry and tussock with intermittent stone slabs. The famous memorial to wartime aircrew sits on the upper plateau, a useful waypoint. Be wary of feral goat sign on the lower slopes — they cross the path frequently.

In winter

Snow drifts deeply into the granite hollows on the broad plateau, and the Knee of Cairnsmore catches lee accumulation from southerlies. The SAIS Southern Uplands area is the formal reference. South-westerly Solway storms drive horizontal sleet for days; full storm shells are appropriate even at this modest altitude.
