Carn Mor
Càrn Mòr — 'the big cairn' — is the heather-clad Corbett of the upper Avon country, rising north-west of Tomintoul on the long ridge running down toward the Cromdale hills. The 804m summit is a small rocky tor on a broad moorland plateau, and the views span from the main Cairngorm plateau in the south to Speyside and the Moray Firth in the north. Drier and friendlier underfoot than the western Highlands, the hill is a good day for parties based at Tomintoul or in lower Speyside.
Gaelic: “cairn-topped hill, big” · Pronunciation: karn more

Park at the small layby near Bridge of Brown on the A939 (NJ128205), the road between Grantown-on-Spey and Tomintoul. Walk south-east along a Land Rover track for around 4km, gaining height steadily across moorland. Where the track curves north, leave it and climb south onto Càrn Mòr's broad north ridge. The summit cairn is reached after a short final pull. Allow 5–6 hours.
Terrain
Decent estate Land Rover track on the long approach. Above the track the going is short heather and grass — drier than most Highland hills thanks to the rain-shadow position east of the Cairngorms. The summit is a small rocky tor on a broad plateau; in cloud the descent line needs accurate bearing.
In winter
Cold easterly winds from the Mearns can be brutal on the broad plateau; snow holds well from January through March. No avalanche concerns on the standard line. The Bridge of Brown layby on the A939 is reliably ploughed but the road itself can close in heavy storms over the Lecht.
This hill is in the Northern Cairngorms SAIS forecast area. Check SAIS forecasts in winter (December–April).
